The zero exponent rule basically says that any base with an exponent of zero is equal to one. For example: x^0 = 1A negative exponent is equivalent to 1 over a positive exponent.x^1 = x x^0 = 1x^-1 = 1/x
(1/2)-5 = 32
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
No, a number raised to a negative exponent is less than 1. When a number is raised to a negative exponent, it is inverted and the exponent becomes positive. This means that the value of the number decreases as the exponent becomes more negative.
If you have a negative exponent, then put 1/the number multiplied by itself the number of times of the exponent. For example: 3-2=1/(3x3)=1/9
