plz solve fast ​

Answer 1

Step-by-step explanation:

1) (625)^(-3/4)

=(25^2)^(-3/4)

=[(5^2)^2]^(-3/4)

=(5^4)^(-3/4)

=5^(-3)

=1/5^3

=1/125

2)(1/216)^(-2/3)

=(1/6^3)^(-2/3)

=[6^(-3)]^(-2/3)

=6^(3*2/3)

=6^2

=36

3)(243/32)^2/5

=[3^5/2^5]^2/5

=[(3/2)^5]^2/5

=(3/2)^(10/5)

=(3/2)^2

=9/4
