Well what you do is you do it normally but you turn the answer of the positive it into the denominator of a fraction and a one as the numerator.
for example -10 to the 4 power is 1/10,000

How do you raise anumber to a negative exponent?
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
Is a number raised to a negative exponent greater than 1?
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.
What is the negative exponent law?
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
What are the rules for a number with a negative exponent?
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.
When is the exponent negative?
When you subtract it from a bigger exponent of another number by dividing two numbers with exponents.
