1. solution :
(81/16)-¾ can be written as (3/2)⁴·-¾
we get (3/2)-³ = -27/-8=27/8.
(25/9)^-3/2 can be written as (5/3)^-3
=(5/3)^-3 = 125/27.
on substituting the values,
=27/8×[125/27÷125/8]
=27/8×27/8
=729/64
2. solution:
³√xy² = (xy²)⅓ = (xy)^⅔
Therefore ,
(xy)^⅔/xy² = x⅔y⅓.
3. Solution:
(5x/5²)(32x/3^-3)=135
(5x/25)(9x/-27)=135
-(5x)(9x)/675= 135
-45x/675= 135
-45x=91125
x= -2025
Hope the answers are correct.
Thank You!☺️
ALL THE BEST.
