In Exercises 59–70, evaluate each exponential expression. - (-1/2)^3

Exponential expressions involve a base raised to a power, indicating how many times the base is multiplied by itself. In the expression (-1/2)^3, the base is -1/2 and the exponent is 3, meaning we multiply -1/2 by itself three times.

When dealing with negative bases, the sign of the result depends on whether the exponent is odd or even. An odd exponent, like 3 in this case, will yield a negative result, while an even exponent would result in a positive value.

To calculate a power, multiply the base by itself as many times as indicated by the exponent. For (-1/2)^3, this involves computing (-1/2) * (-1/2) * (-1/2), which requires careful handling of both the numerators and denominators.
