ASVAB Arithmetic Reasoning Operations on Exponents Practice Test 981180

Question 1 of 5
Negative Exponent

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 x-5 to remove the negative exponent.

\( \frac{-1}{-5x^{5}} \)
\( \frac{1}{x^5} \)
\( \frac{1}{x^{-5}} \)
\( \frac{-5}{x} \)
