Mistake had occurred in step 1): it should be LHS =4^[5(x-3)]=2^[2*5(x-3)]=2^[10(x-3)] RHS=32^(2x)=2^[5*(2x)]=2^[10x] Thus, 10x-30=10x => -30=0 is a contradiction => the equation has no solution.

RHS = 2tan(2x)sin²(x) = tan(2x){1 - [1 - 2sin²(x)]} = tan(2x)[1 - cos(2x)] = tan(2x) - tan(2x)cos(2x) = tan(2x) - sin(2x) = LHS

Yep, ordinary algebra. Divide both sides by the same value and the equation remains balanced. The LHS still = the RHS. So divide away and enjoy.
