Question

Find the value of:(chapter =exponents)
.(-1/4)raised to 4
.(-4/7)raised to 2
.(-2/7)raised to 3
.(-1/2)raised to 5

Answer 1

hey there

let's do with the basic.

when the raised power is even {eg.-》2,4,6}

the minus sign will become plus.

so let's solve the ques:

$1) (\frac{ - 1}{4})^{4} = \frac{1}{256} \\ 2)( \frac{- 4}{7}) ^{2} = \frac{16}{49} \\ 3)( \frac{ - 2}{7} )^{3} = \frac{ - 8}{343} \\ 4) (\frac{ - 1}{2})^{5} = \frac{ - 1}{32}$

hope it help
