Answer:

#1/b^15#

Explanation:

Put simply, a negative exponent just makes a variable go from the numerator to the denominator or vice versa.

A bit deeper, using the power property of exponents we know that #b^-15 = (b^15)^-1# and since #x^-1# means #1/x#, if we substitute #b^15# for x then we have our answer.
