2.
When a number is raised to a negative power, move it to the other side of the fraction.
So, (0.5)^(-1) is the same as
(1)/(0.5)^(1)
or 1/(1/2).
from there, just divide the fractions, and you will be left with 2.

5-1 = 1/5
(1/2)-5 = 32
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
I assume you mean "negative integer exponents".It means that: * It is an exponent * It is an integer (whole number) * It is negative (less than zero, i.e., with a minus sign) A negative exponent is defined as the reciprocal of the positive exponent. For example, 10 to the power -5 is the same as 1 / (10 to the power 5).
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.
