Question

For any positive numbers a, b, and d, with b 1, logb _____ = d logb a

Answer 1

Sorry to be picky, but your " b 1, logb _____ = d logb a" is hard to interpret.
Please, if y ou haven't already tried out the Draw utility (below), try it now, using it to express your " b 1, logb _____ = d logb a" exactly as it appears in the original problem statement. Thanks.

@mathmale i think in this way this make sens :

logb a^d = d logb a
