Question

by using identity evaluate (8+1/8 - 125/8)​

Answer 1

Answer:

( 2/5 )^ 9

Step-by-step explanation:

( 8/125 )^ -1/3

we know the identity that

-a = 1/a

-1/a = a

so

( 8/125 )^ 3

([ 2/5 ]^3)^3

and we also that

[(a)^n]^n = n×n

it means that the power will multiply

so

( 2/5 )^ 3×3

( 2/5 )^ 9

HENCE THE ANSWER IS ( 2/5 )^9
