-4 to the second power is 16
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
Calculate the powers, and do the addition. For example, the second power of 4 is the same as 4 x 4 (you are supposed to multiply 4 by itself).
4,096 or 4 to the sixth power. When multiplying numbers with powers you add the powers if the whole number is identical. 4 squared x 4 squared is 64, x 4 squared is 4096
4 to the second power
-32 = -(32) = -9 (-3)2 = 9 The difference is 9 - (-9) = 18.
4 x 4 = 16
The answer is 256.
(-4)(-4) or (-4)2
