For example, 10 to the power -5 means the same as 1 divided by (10 to the power 5). In general, you can interpret negative exponents this way, with reciprocals.

Find the reciprocal of the positive exponent. Thus, x-a = 1/xa

A negative exponent is simply the reciprocal of the positive exponent. So simply remove the negative sign and find the reciprocal. Thus, for example, 5-3 = 1/53 = 1/125

A negative exponent means the same as a positive exponent in the denominator. Thus, x-0.5 = 1/x0.5. This, in turn, is equivalent to 1/(square root of x).

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

A negative exponent implies a reciprocal.Thus x^-a = 1/x^a or, equivalently, (1/x)^a

Example: (4x)-2 The answer to this would be 1/ 16x2. Multiply it out as if the negative exponent was not there ((4x)2), then that will be the denominator of the fraction. The numerator is one.
