A number with a negative exponent should be treated as the reciprocal of that same number with the analogous positive exponent. For example, 42 = 16, but 4-2 = 1/42 = 1/16.

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
It will become a positive number.
When you subtract it from a bigger exponent of another number by dividing two numbers with exponents.
