Answer:
Step-by-step explanation:
We want to find an equivalent expression for
To find an equivalent expression, we need to apply the following property of exponents:
We let a=9, n=4 and m=½x
Then :
Simplify the left hand side to get:
Therefore the correct answer is:
7u^3 - u^2 - 7 + 2u^3 - 4u^2
(7+2)u^3 -(1+4)u^2 - 7
9u^3 - 5u^2 - 7
4^-3 equals 1/64. Hope this helps!
The answer is false I took geometry last year
