You have written 0 = 4x.
The value of x that makes it true is x = 0, given that 4 times 0 is 0.
Nevertheless, I think you wanted to write 0 = 4 ^x (this is 4 raised to the power 4).
In that case, there is not any valued of x that satisfies the equation. This is, the equation is always false.
That is because, there is not any value of x for which 4^x is zero. The range of this function is al the positive values of x, which exclude zero.

Answer is 72
Step by step
Using order of math rules of PEMDAS, we do the inner parentheses “P” first, working outwards with parentheses and then exponents, multiply and divide, add and subtract.
2x [4x(2+1)x3] add inner parentheses
2 x [4 x 3 x 3] multiply inside brackets
2 x 36 multiply for your answer
= 72
