Step-by-step explanation:
(c) (2/3)^2×(2/3)^6=(2/3)^6
= using the algebraic identity
= x^a×x^b= x^a+b
= (2/3)^2+6= (2/3)^6
= (2/3)^8 = (2/3)^6
= let take 8as x
= 8x=6
= x= 6/8=3/4
(d) ((2/5)^3)^2=(2/5)^2x
using the exponent identity
((x)^a)^b= (x)^ab
= (2/5)^6=(2/5)^2x
using the identity (x)^a=(x)^b=a=b.
6=2x we can take 2x on left side.
2x=6
x=6/2= 3
