One possibility is to take the ##\log_2## of both sides of the equation.

Could you find x given axbx=c?

would it be

log(a^b^c) = x * x ?

This is not even remotely close. You need to review the properties of exponents. A web search on "properties of exponents" or "laws of exponents" should be enlightening.

One of the properties I found is :

x^a * x^b = x^(a+b)

but how would I use that property since I have two different coefficient values?

That is not the property you need here.
Let me ask a different question... how else might you write (xy)a?

You can write 2t-1=2t * 2-1 and 6t-2=6t * 6-2.
