Question

A fraçao de (8/7) elevado ao 0
E (4/3) elevado ao -4

Answer 1

8/7^0=1
(4/3)^-4=3/4^4=81/256

Answer 2

Olá

$(\dfrac{8}{7})^{0} = \dfrac{8^{0}}{7^{0}} = \dfrac{1}{1} = 1$

$(\dfrac{4}{3})^{-4} = \dfrac{1}{(\dfrac{4}{3})^{4}}$
$\dfrac{1}{\dfrac{4^{4}}{3^{4}}}=\dfrac{1}{\dfrac{256}{81}}=\dfrac{81}{256}$
