Question

calcule a)4^5/4^3 b) -4^5/4^3 c) -4^5/-4^3 d) (4^2)^3/4^5​

Answer 1

Resposta:

a)16

b)-16

c)16

d)4

Explicação passo-a-passo:

$a)\frac{4^{5}}{4^{3}}=4^{5-3}=4^{2}=16\\b)-\frac{4^{5}}{4^{3}}=-4^{5-3}=-4^{2}=-16\\c)\frac{-4^{5}}{-4^{3}}=\frac{4^{5}}{4^{3}}=4^{5-3}=4^{2}=16\\d)\frac{(4^{2})^{3}}{4^{5}}=\frac{4^{2*3}}{4^{5}}=\frac{4^{6}}{4^{5}}=4^{6-5}=4^{1}=4$
