evalute the expression

Do these expressions equal?  If you are asking what does 23 equal, then it is 2X2X2= 8.  -7 =-7.

Are you perhaps using logarithms?

Hey Connie -

2 to the power of 3 does not equal -7.  Are you sure you have the whole equation, or is something missing?

As John R. stated:  2^3=8  -7 does NOT = 2^3
