Hello, MathClown!
Exactly where is your difficulty?
We have: .
Always remember the order of operations: PEDMAS ...Parenthesis, Exponents, Multiplication/Division, and last of all Addition/Subtraction.
So in the equation (2a^2x)^2 ....we look to the parenthesis 1st ...(2*2^2*3)....
exponents come next -->(2*4*3)=24 ,
then 24^2=576.
