When a = 2 and x = 3

The book states the answer as 576, but I can't see how that figure derived.

Thank you!

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. - Jan 22nd 2013, 11:27 PMProve ItRe: Help With Simple Expression
