Question

Simplify and leave the answer in index form (−4a⁻³)².

Answer 1

Given that: 

We need to find the value of (−4a⁻³)²

Let us first multiply the index -3 with 2, we get

−3×2 = −6

Now, we need to simplify −4²

−4² = −4 × −4 = 16

So, (−4a⁻³)²

= 16a⁻⁶

= 1/16a⁶

Therefore, the value of (−4a⁻³)²is 1/16a⁶.
