In aba^bab, which quantity is the base and which is the exponent?
A
A negative exponent gives a reciprocal: a−n=1an\boxed{a^{-n}=\frac{1}{a^n}}a−n=an1.
B
Base: aaa; exponent: bbb.
C
Since 1x=11^x=11x=1 for every xxx, the exponent is not unique.
D
The vertical asymptote of y=logaxy=\log_a xy=logax is x=0\boxed{x=0}x=0.
