Answer 2

Answer:

hii

hope it will help you

Step-by-step explanation:

Express 3125 as a product of prime

3125 = 5 × 5 × 5 × 5 × 5 = 5^5

We know that

_________________

1 )( a / b )^ -m = ( b / a ) ^ m

2) a^m / b^m = ( a / b )^ m

Now ,

( 0.03125 )^ -2/5

=( 3125 /10000 )^-2/5

= ( 10000 / 3125 )^ 2/5

= [ ( 10 )^5 / 5^5 ]^2/5

=[ ( 10 / 5 )^5]^ 2/5

= (2^5 ) ^ 2/5

= 2^( 5/1 × 2/5)

= 2^2

= 4

Therefore ,

( 0.03125 )^ -2/5 = 4
