Question

Determine o valor de cada expressão 2 elevado -5 + 2 elevado -3

Answer 1

Olá, Raimundete!

$( \frac{1}{2})^5 + ( \frac{1}{2})^3 = \frac{1}{32} + \frac{1}{8} = \frac{1+4}{32} = = \boxed{ \frac{5}{32}}$

Answer 2

$2^{-5} + 2^{-3}= (\frac{1}{2})^5 + ( \frac{1}{2}) ^{3}=$

$= \frac{1}{32}+ \frac{1}{8}= \frac{1+4}{32}= \frac{5}{32}$
