7 x 7 = 49
2^7 = 2x2x2x2x2x2x2 = 4x4x4x2 = 16x8 = 128
42 = 4*4 = 16
32 4 plus 2 the third power -3 cannot be evaluate.
Evaluate: -7 - 8
54
Multiply (4) x (4) x (4) and get 64 .
4^3 = 4*4*4 = 16*4 = 64
You evaluate the power of the power first. For example, 4 to the power of (3 to the power of 2) is 4 to the power of 9 which is 262,144
What is 1+2 with sum
(3 times 2) + 4 times (7-1) = 30
