X ^ 2 - 9
= x ^ 2 - 3 ^ 2
It turns into 3 ^ 2

remember the formula :
a^2 - b^2 =(a+b)(a-b)

Answer:
64
Step-by-step explanation:
first, we'll start with the value inside the parenthesis, which is 2³
2³ means to multiply 2 by itself 3 times
so it would be

now we need to do (8)², which is to multiply 8 by itself twice
8*8=64
hope this helps!
