Ответ:
Option A is correct.
A) 64
Step-by-step explanation:
Given:
The given expression =![\frac{(-1^5)^2}{(-2^{-3})^2}](/tpl/images/0456/6968/0fca8.png)
Now we need to simplify the given expression.
Solution:
=![\frac{(-1^5)^2}{(-2^{-3})^2}](/tpl/images/0456/6968/0fca8.png)
Rewrite the expression as.
=
-------(1)
First we expand numerator![(-1)^{5}=(-1\times -1)\times (-1\times -1)\times -1](/tpl/images/0456/6968/57f22.png)
Similarly we simplify the denominator
.
Now we substitute
and
in equation 1.
Negative sign is cancelled.
So we write the equation as.
Therefore the answer is 64
