Simple! The value of 4 is four. It equals 4.
You evaluate the powers of 10 and a exponent of positive 4.
Evaluate means to "find the value" of. It is similar to the old question, "what is 10 plus 4?" Evaluate (10+4) should evoke the the same answer.
Unfortunately there is no expression to evaluate!
Evaluate: -7 - 8
42 = 4*4 = 16
4 cubed is 64
Evaluate -6 to the power of 2
the answer is 5
-x+ 4 for x = 6.
12.82
4^3 = 4*4*4 = 16*4 = 64
Multiply (4) x (4) x (4) and get 64 .
