-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
4 x 4 = 16
The answer is 256.
18x^8y^4
In classical times, the second power was described in terms of the area of a square. This led to the use of the term squareto mean raising to the second power.
2 to the second power is 4, which isn't a factor of 54. 3 to the second power is 9, which is a factor of 54 but isn't prime. 4 divided by 9 is 4/9, which isn't prime and isn't a factor of 54.
Is basically doubling the number. For example 2 to the second power is 4.
