the question asks us to rationalise the given expression !
so let's start ~
[tex] \frac{6 - 4 \sqrt{3} }{6 + 4 \sqrt{3} } \\ \\ \implies \: \frac{6 - 4 \sqrt{3} }{6 + 4 \sqrt{3} } \: \times \: \frac{6 - 4 \sqrt{3} }{6 - 4 \sqrt{3} } = \frac{(6 - 4 \sqrt{3}) {}^{2} }{6 {}^{2} - 4 \sqrt{3} {}^{2} } \\ \\ \implies \frac{\: 6 {}^{2} + 4 \sqrt{3} {}^{2} - (2 \times 6 \times 4 \sqrt{3} )}{36 - 48} \\ \\ \implies \: \frac{36 + 48 - 48 \sqrt{3} }{ - 12} \\ \\ \implies \: \frac{84 + 48 \sqrt{3} }{ - 12} \\ \\ \implies \: \frac{ \cancel{- 12}(7 - 4 \sqrt{3} )}{ \cancel{ - 12} } \\ \\ \implies \: 7 - 4 \sqrt{3} [/tex]

Answer:
-7+4√3.
Step-by-step explanation:
6-4√3 / 6+4√3 Multiply top and bottom by 6-4√3:-
= (6-4√3)( 6-4√3) / (6+4√3)(6- 4√3)
= (36-24√3- 24√3+48) / (36-48)
= (36-48√3+48) / (-12)
= -3 +4√3 - 4
= -7 + 4√3.
Which inequality best represents the phrase?
A number less then 0
A. n=0
B. n greater than n 0
C. n greater then n with a underscore on the bottom 0
D. n greater than 0 with a underscore 0
Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.
Answer:
n < 0
Step-by-step explanation:
Given that:
A number less than 0
Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.
From the following answer chioce:
[A] n=0
[B] n greater than n 0
[C] n greater then n with a underscore on the bottom 0
[D] n greater than 0 with a underscore 0
We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.
I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.
< → less than
> → greater than
A number less than 0 ⇒ n < 0

Which is the expression is equivalent to 27/125
a (3/5)3
b 3/5'3
c (3/4)2
d(3'3/5'5)
Answer:
a
Step-by-step explanation:
(3/5)^3= 27/125
So a is the correct answer
Answer:
Answer option D.
I'm assuming you meant (3/5)'3 for option A.(3/5)^3 also known as (3/5)'3 in your case.If we simplify the expression (3/5)^3 we can see that ^3 means you cube both the numerator and the denominator since 3/5 is in parenthesis.
Numerator:
3 cubed(3^3) would result in
= 9
Denominator:
5 cubed(5^3) would result in
= 125
Hence, you'll get 9/125.
So your answer is;
A, (3/5)'3If sin p =3/5 and p is an acute angle, what is the value of tan p?
Answer:
sin x + cos x = 5/13 + 12/13
Step-by-step explanation:
Given that tan x = 5/12, what is the value of sin x + cos x?
draw a triangle with opposite leg=3 and hypotenuse=5
tan p = opposite/adjacent = 3/4
similarly, in a 5-12-13 right triangle
sin x + cos x = 5/13 + 12/13
The probability of an event is P(A) = 0.05 What is the complement of P(A)?
Probability is the likelihood or chance that an event will occur. The complement of the probability will be 0.95
What is probability?Probability is the likelihood or chance that an event will occur. Mathematically:
Probability = expected outcome/total outcome
Given that the probability of an event is P(A) = 0.05, the complement will be expressed as:
P'(A) = 1 - P(A)
P'(A) = 1 - 0.05
P' (A) = 0.95
Hence the complement of the probability will be 0.95

what is the value of (-2)6
with the six as a small number like ³
Answer:
64
Step-by-step explanation:
(-2)^6
6 is an exponent and basically it tells us to multiply the base, -2 by itself 6 times
so (-2)^6 is the same as saying -2 × -2 × -2 × -2 × -2 × -2
-2 × -2 × -2 × -2 × -2 × -2 = 64 so the value of (-2)^6 is 64

express 194720 in standard form correct to 3 significant figures
Answer:
1.95 x 10^5
Step-by-step explanation:
First look at the 4th digit in the number 194720 as the the question said to round to 3 significant figures. If the 4th digit is more than 5, then add 1 to the third digit which results in 195000. Now the question also said to express in standard form. Look for the first non-digit number in 195000. After 1 put a decimal point and remove all the zeros after the point which results in 1.95. Now count how many digits you moved to the left which comes as 5. Write the answer as 1.95 x 10^5.
