(-8x9)2

1 answer

When simplifying the expression (-8x^9)^2, we need to raise both the coefficient (-8) and the variable (x^9) to the power of 2.

First, let's simplify the coefficient:
(-8)^2 = 64

Now, let's simplify the variable:
(x^9)^2 = x^(9*2) = x^18

Putting it all together, we have:
(-8x^9)^2 = 64x^18
