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

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

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 you subtract it from a bigger exponent of another number by dividing two numbers with exponents.

Because a number to the exponent 0 = 1 and any lesser exponent decreases the value.

A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100

That number becomes an exponent. For example, 5 to the -2 power is 1/25

It will become a positive number.

it would be a negative multiplied by a negative and your answer should end up positive.

turn the positive number into its recipricol and the put the number of the negative number on the top

The exponent will be negative when the absolute value of the number is between 0 and 1. For example, 1X10-1 is 0.1.
