The expression (3x^7)^4 is equivalent to cx^n.What is the value of c?

Answers

Answer: It’s 81

Step-by-step explanation:

I think it’s 81 because u use the distributive property (xy)^a=x^a y^a

and in the situation you change it into 3^4(x^7)^4 and u simplify 3^4 and get 81 and then just multiply 7 and 4 and your answer is 81x^28. 81 is c in the equation

We want to find an equivalent expression to  (3x^7)^4 of the form cx^n, and we want to find the value of c.

The equivalent expression is:

[tex]81*x^{28}[/tex]

So the value of c is:

c = 81.

First, we need to remember two properties of exponents.

The exponents are distributive under multiplications.

And we know that:

[tex](a^n)^m = a^{n*m}[/tex]

Using these two properties, we can rewrite:

[tex](3x^7)^4 = (3^4)*(x^{7*4}) = 81*x^{28}[/tex]

So the equivalent expression is:

[tex]81*x^{28}[/tex]

Then we have c = 81.

Explain how to convert percent to fractions and percents and decimals
PLEASE YELP IM ON A TEST!!!

Answers

Percents to a decimal is easier to understand just take the percent so say it is 35% the decimal form would be .35 or 5% .05, and for the percent to a fraction just take the percent such as 30/100 and make sure it is in the simplest form to solve so that would be 3/10.

If f(x) = 2x - 5 , Find f(3).
Substitute 3 for x then type your final answer.

Answers

Answer:

f(3) = 1

Step-by-step explanation:

To find f(3), plug in 3 as x and simplify the expression:

f(x) = 2x - 5

f(3) = 2(3) - 5

f(3) = 6 - 5

f(3) = 1

So, f(3) = 1

The properties of similar triangles.

In Geometry, two (2) triangles are said to be similar when the ratio of their corresponding sides are equal and their corresponding angles are in congruence.

By applying the properties of similar triangles, we have this expression:

Question 12 (1 point) Johnny says the sequence below is (A) Arithmetic because it has a common difference. He also says the first term is 100. (B) Do you agree? a 65 – 100n (A) Is it arithmetic? (B) is the first term 1007 if not what is the first term?​

Answers

Answer:

The sequence is Arithmetic because it uses subtraction.

The first term is a(1) = 65 since it comes first in the formula.

Step-by-step explanation:

We are given the equation 65-100n. 65 is the first term since it comes first in the arithmetic formula and 100n is the common difference. So the correct answer should be an arithmetic sequence and 65 as the first term.
