SOLUTION: Here is my question:
7^logx = 7
the answer is 10, but I am not quite sure what to do when the log is an exponent of 7. I'm also supposed to show a check of my answer.

You can put this solution on YOUR website! Recall this about logarithms:
If , the bases are the same, that is a = a, then the exponents are equal, therefore x = y. Applying this to your problem:
The bases are the same so the exponents are equal.
Change to exponential form.
Recall that log(x) is log to the base 10 of x:
Logarithmic form: y = log(x)...Exponential form: x = 10^y
So, x = 10
Check: but log10 = 1
