Hi ,
( 3/2 )^6 × ( 4/9 )^5 = ( 2/3 )^x+2
( 3/2 )^6 ×[ ( 2/3 )² ]^5 = ( 2/3 )^x+ 2
( 3/2 )^6 × ( 2/3 )^10 = ( 2/3 )^x+2
[since ( a^m )^n = a^mn ]
( 2/3 )^-6 × ( 2/3 )^10 = ( 2/3 )^x+2
[ since ( a/b )^n = ( b/a )^-n ]
( 2/3 )^-6+10 = ( 2/3 )^x+2
[ since a^m × a^n = a^m+n ]
( 2/3 )⁴ = ( 2/3 )^x+2
4 = x + 2
[ If a^m = a^n then m = n ]
4 - 2 = x
2 = x
Therefore ,
x = 2
I hope this helps you.

Given : (3/2)^6 * (4/9)^5 = (2/3)^x+2
=>
= > 4 = x + 2
= > 4 - 2 = x
= > x = 2.
Hope this helps!
