When multiplying two powers, if their bases are the same, then you simply add the exponents:
[tex]\frac{8^5*8^3*8^2}{8^8} =\frac{8^{5+3+2}}{8^8} =\frac{8^{10}}{8^8}[/tex]
When dividing two powers, if their bases are the same, you simply minus the exponents.
[tex]\frac{8^{10}}{8^8}=8^{10-8}=8^2[/tex]
Thus when the expression is simplified, the answer as a power is [tex]8^2[/tex]
Answer: 8^2

The sum of three numbers is 78. The third number is 7 more than the first. The second number is 3 times the third. What are the numbers?
Answers
Answer:
10+51+17=78
Step-by-step explanation:
Alright, so at first I just took a random number and kept on working it out until I got the exact answer as 78. Finally, i got the third number as 17. Now, i know the third number is 7 more than the first so I have to subtract 17 and 7, 17-7=10. So the first number is 10. Ok, now i know that the second number is 3 times the third number (17) so you should multiply, 17x3=51. 51 is the 2nd number.
1st number=10
2nd number=51
3rd number=17
Add them, 10+51+17=78.
Answer:
First number = 10Second number = 51Third number = 17Step-by-step explanation:
In the question we are given ,
Sum of three numbers is 78Third no. is 7 more than firstSecond no. is 3 times thirdSo , we are assuming that ,
Let first no. be xThird no. be x + 7 ( because in question it is given that third number is 7 more than the first number ) .Second no. be 3 ( x + 7 ) ( because in the question it is given that second no. is three times the third )We are finding the solution by adding all these term and equating it with 78 because sum of these three numbers is equal to 78 .
Here we go ,
[tex] \longrightarrow \: x + 3(x + 7) + x + 7 = 78[/tex]
Step 1 : Solving the bracket part :
[tex] \longrightarrow \: \blue{x }+ \blue{ 3x} + \red{21} + \blue{ x} + \red{7 }= 78[/tex]
Step 2 : Adding like terms :
[tex] \longrightarrow \:5x + 28 = 78[/tex]
Step 3 : Transposing 28 to right hand side :
[tex] \longrightarrow \:5x = \green{78} - \green{28}[/tex]
Step 4 : Subtracting 28 from 78 :
[tex] \longrightarrow \:5x = 50[/tex]
Step 5 : Transposing 5 to right hand side :
[tex] \longrightarrow \:x = \cancel \frac{50}{5} [/tex]
Step 6 ; Cancelling 50 with 5 :
[tex] \longrightarrow \: \purple{\boxed{x = 10}}[/tex]
Therefore value of ,
x [ first number ] = 103(x + 7 ) [ second number ] = 51x + 7 [ third number ] = 17Verification :
We are verifying our answer by adding the three numbers and it must be equal to 78 .
10 + 51 + 17 = 7861 + 17 = 7878 = 78L.H.S = R.H.SHence , Verified.Therefore , our answer is correct .

Giselle made several apple and peach pies. She bought peaches for $4 per pound and apples for $2 per pound. If Giselle spent $60 to buy 24 pounds of fruit, how many pounds of peaches did she buy?
Answers
The number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds
Given:
cost of peaches per pound = $4
cost of apples per pound = $2
Total amount spent = $60
Total pounds bought = 24
let
x = number of peaches
y = number of apples
x + y = 24 (1)
4x + 2y = 60 (2)
multiply (1) by 2
2x + 2y = 48 (3)
4x + 2y = 60 (2)
subtract (3) from (2)
4x - 2x = 60 - 48
2x = 12
x = 12/2
x = 6
substitute x = 6 into (1)
x + y = 24 (1)
6 + y = 24
y = 24 - 6
y = 18
Therefore, the number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds

So, a.0, b.1/10, c.81, d.1/64
Step-by-step explanation:
Part A, anything raised to the power of zero is equal to zero. So suppose we have a constant, b, and we raise it to the power of zero, so b^0, it'll always be 0.
Part B, a negative power essentially means that you'll have to inverse the number. Once again, if we have a constant, b, and we raise it to the power of -1, it'll end up being 1/b. So b^-1 = 1/b.
Part C, its simply just multiplying 3 with itself four times.
Part D, as mentioned before, anything raised to a negative power means that you need to inverse the number. So 4^-3 is equal to 1/4^3, meaning that its just 1/64.

Byron is conducting an experiment to determine whether a new medication is effective in reducing coughing. He finds 1,200 volunteers with coughing issues and divides them into two groups. The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of coughing. What can Byron conclude from this experiment?
Answers
Answer:
Step-by-step explanation:
Given Byron's discovery of 1,200 volunteers with coughing problems.
He separates them into two categories:
1. There is no medication given to the control group.
2. The medication is given to the treatment group.
In addition, patients in the treatment group have fewer signs of coughing. As a result, Byron can conclude that the new medication works in the treatment group to reduce coughing.
The medicine given to the people, according to Byron, worked because the treatment group showed signs of less coughing.
Answer: Deduction is the effectiveness of the medication is positive since purpose for the trial was achieved. The cough symptoms responded to the medication while the control method used on the other group yielded no visible result. Medication was a better choice to the control method
Step-by-step explanation: Those who received the medication had their symptoms reduced while those who had other control measures showed no form of improvement.

What are the solutions to the equation y = 4x2 +5x−6?
Answers
Answer:
Option D: x = -2; x = 3/4
Step-by-step explanation:
Hello!
We can factor this expression and then find the zeroes to find our solutions.
Factor:We have to factor by grouping. Multiply the 1st and last term, 4x² and -6 is -24x², and find two factors that equal to -24x² and add up to the second term, 5x. 8x and -3x work for this.
y = 4x² + 5x - 6y = 4x² + 8x - 3x - 6y = 4x(x + 2) - 3(x + 2)y = (4x - 3)(x + 2)Zero-Product PropertyNow, set the equation equal to zero.
0 = (4x - 3)(x + 2)Remember, if two numbers, a and b, multiply to 0, either a or b or both numbers must be zero. So now we set both factors to zero, hence the zero-product property.
4x - 3 = 04x = 3x = 3/4And the next one:
x + 2 = 0x = -2The solutions are x = -2, and x = 3/4, or Option D
