Question

Find he value of x : (3/5)^x (5/3)^2x = 125/27

Answer 1

Answer:

x = 3

Step-by-step explanation:

( 3 / 5 ) ^x x ( 5 / 3 ) ^ 2x = 125 / 27

==> ( 5 / 3 ) ^ 2x x ( 5 / 3 ) ^ -x = 125 / 27

==> ( 5 / 3 ) ^ x = ( 5 / 3 ) ³

==> x = 3 since , if bases are equal and L.H.S and R.H.S are equal , then powers are equal .
