i graphed to on desmos.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
