You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
Put the number with the exponent in the denominator of a fraction and take off the negative symbol. The numerator in that fraction should be 1. Example: 8-2 Converts to: 1 --- 82
by doing reciprocal
If the numerator is negative and the denominator is positive then the fraction will be negative. If the numerator is negative and the denominator is negative too then the fraction will be positive.
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
A negative exponent simply means that the base is on the wrong side of the fraction line.For example, if you have x-2, you can turn this into a positive exponent by moving the base to the denominator and changing the sign on the exponent. The result would be:1--x2
You look at the denominator first. Then you try to find out what exponents make the denominator. After doing that, you add a negative symbol to the smaller number on the exponent.
Put the number with the exponent in the denominator of a fraction and take off the negative symbol. The numerator in that fraction should be 1. Example: 8-2 Converts to: 1 --- 82
Make it a fraction, flip the numerator and denominator, and the exponent is no long negative. For example 4-3 = 1/43 = 1/64
Variable exponents.
Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.
Negative exponents are used to represent 1 divided by an a base to a specific exponent.
Any value to the zero power is 1. If an exponent is negative, you need to switch it from the numerator to the denominator or vice-versa. For example, x-2 is 1/x2.
why the exponents can not be negative
When multiplying numbers with exponents, you add the exponents.

If the numerator is negative and the denominator is positive then the fraction will be negative. If the numerator is negative and the denominator is negative too then the fraction will be positive.
