Respuesta :

Answer:

[tex]\frac{1}{2^{10}} \ and\ \frac{1}{1024}[/tex]

Step-by-step explanation:

Given

[tex](2^{5})^{-2}[/tex]

Required

Find the equivalent;

To find the equivalent of the given expression, we make use of laws of indices;

Using the following law of indices;

[tex](a^m)^n = a^{m*n}[/tex]

So;

[tex](2^{5})^{-2}[/tex] becomes

[tex](2^{5})^{-2} = 2^{5*-2}[/tex]

[tex](2^{5})^{-2} = 2^{-10}[/tex] ------------ This is one equivalent

Solving further;

Using the following law of indices;

[tex]a^{-m} = \frac{1}{a^m}[/tex]

So;

[tex](2^{5})^{-2} = 2^{-10}[/tex] becomes

[tex](2^{5})^{-2} = \frac{1}{2^{10}}[/tex]

[tex]2^10 = 1024[/tex]

Hence;

[tex](2^{5})^{-2} = \frac{1}{1024}[/tex]

Conclusively; the equivalents of [tex](2^{5})^{-2}[/tex] are [tex]\frac{1}{2^{10}} \ and\ \frac{1}{1024}[/tex]
