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

a negative exponent simply indicates that the term is the reciprocal of the given value. x to the power of negative 2 is 1/x^2
7.810 to the negative 2 power in standard notation is written as 0.07810
1/64
30
-1/32
Yes
its 16, because the value of the power is even so the negative has no effect.
2-2 = 1/4
