Condense the logarithmic expression and simplify. log base 3x (x)−2⋅log base 3x (3)−3⋅log base 3x (x)

Solve the equation for x.3(6x - 1) = 12 i've tried doing the math and i can't find out what i'm doing wrong

For g(x) = 5x - 3 and h(x) = [tex]\sqrt{x}[/tex], find (g · h)(4)

Can someone, me with this. i really need with this
