Verified answer
( 7/12)^-4 × ( 7/12)^3x = (7/12)^5we know
if a^m × a^n then , we can write this
a^(m + n) .
e.g a^m × a^n = a^(m + n)
now use this ,
( 7/12)^-4 × (7/12)^3x = (7/12)^5
(7/12)^( -4 + 3x ) = (7/12)^5
(-4 + 3x ) = 5
3x = 5+ 4= 9
x = 3
(7/12)^-4+3x = (7/12)^5
equating powers
-4 +3x = 5
x=3
