A negative power/index/exponent simply inverts the expression and the power now becomes a positive number.
2-1 = 1/21 = 1/2 = 0.5
Note : This also applies if the term is the denominator.
For example : 1/3-2 = 32 = 9.
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
Negative 12 to the power of 2 is -144
2 to the negative 6th power as a fraction = 1/64
It is always negative when raised to an odd power and always positive when raised to an even power -2 to the third power = -2 x -2 x -2 = -8 -2 to the fourth power = -2 x -2 x -2 x -2 = +16
1/64
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
negative 0.0016
-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.
1
Negative 12 to the power of 2 is -144
Three fourths to the negative first power is 1.33333333333
2 to the power of negative one is equal to 0.5
3
5.3 times ten to the negative first power is 0.53
A half ( 20 = 1, so 2 to the (0 - 1) = 1/2)
2 to the negative 6th power as a fraction = 1/64
2-4 = 16
