2¹ = 2
-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.
5^2
2 raised to the first power is equal to 2. In mathematical terms, this means that when you multiply 2 by itself zero additional times (since the exponent is 1), the result remains 2. Therefore, ( 2^1 = 2 ).
If you have 3 to the power 2 to the power 2, without any parentheses, you have to calculate from right to left. In this case, calculate 2 to the power 2; then calculate 3 to the power (whatever the result you get). If there are parentheses, do the calculation in parentheses first.

2¹ = 2
When something is to the negative first power, you find the inverse of it - which means you flip the fraction. (1/2)^-1=2/1 2
-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.
Any number to the 1st power is the same number, unchanged. Two to the 1st power is 2.

246 This is interesting!
Simpley, 2(to the power of)3 as there are 3 2's after the first :-)
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
