Question

URGENTEEEE!!!! 30 PONTOS

Dadas as funções definidas por:
$f(x) = {(4\5)}^{x} e \: \: g(x) \: = {(5\4) }^{x}$
Qual e o valor de g(1) . f(-2)?​

Answer 1

f(x) = (4/5)^x. g(x) = (5/4)^x

f(-2)= (4/5)-². g(1) = (5/4)¹

f(-2)= (5/4)². g(1) = 5/4

g(1) . f(-2) =

(5/4). (5/4)²

(5/4)³

125/64
