A negative exponent indicates the number of times that the base is divided by itself. To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal: \(b^{-e} = { 1 \over b^e }\). For example, \(3^{-2} = {1 \over 3^2} = {1 \over 9}\)
Convert b-5 to remove the negative exponent.
\( \frac{-5}{-b} \) | |
\( \frac{-5}{b} \) | |
\( \frac{5}{b} \) | |
\( \frac{1}{b^5} \) |
