Step 1.1
Simplify 3log9(x2) by moving 3 inside the logarithm.
log9((x2)3)=6log9(x)
Step 1.2
Simplify 6log9(x) by moving 6 inside the logarithm.
log9((x2)3)=log9(x6)
log9((x2)3)=log9(x6)
Step 2
For the equation to be equal, the argument of the logarithms on both sides of the equation must be equal.
(x2)3=x6
