Question

(-4)^5÷(-4)^8 please help me​

Answer 1

1/64

Step-by-step explanation:

-4^5/-4^8= 4^5-8

= 4^-3

= 1/64

Answer 2

$\begin{gathered}\\ \sf\longmapsto (-4)^{5}\div (-4)^{8}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto (-4)^{-3}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -4^{-3}\end{gathered}$

☣️Express with a positive exponent using $a^{-n}=\frac{1}{a^{n}}$

$\begin{gathered}\\ \sf\longmapsto - \frac{1}{4 ^{3} } \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto - \frac{1}{64}\end{gathered}$
