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-3 to remove the negative exponent.
| \( \frac{-3}{-b} \) | |
| \( \frac{-3}{b} \) | |
| \( \frac{1}{b^3} \) | |
| \( \frac{3}{b} \) |
