Please Help: How to solve log₇ (49x) with the instructions below

Use the product rule to expand the logarithmic expression. Evaluate logarithmic expressions.

log(base7) 49x
= log(base7) 49 + log(base7) x
= log(base7) 7^2 + log(base7) x
= 2 log(base7) 7 + log(base7) x
= 2 + log(base7) x

hope this helps...
