Answer 1

Hello,

 

Is the question (2x)3 + 23x?  You had a space between the 2 and the 3 at the end- I'm not sure if that is a 23 or if you are missing something there.

 

Anyway, remember the order of operations: Please Excuse My Dear Aunt Sally:

Do Parentheses first, then Exponents, then Multiplication/Division and then Addition/Subtraction last.

 

So you would start with the parentheses:  2x times 3 = 6x.  Then add 6x + 23x = 29x.  :)

Answer 2

 (2x) 3 + 2 ( 3x)=

 

  6x + 6x =12x
