Are you sure breaking down 7^x^2 is the only way?
Try cross multiplying it to the other side and observe.

Is the numerator supposed to be 72x + 3 or 72x + 3 or 72x + 3?

I suspect that it's the first. If that's what you meant, write it as 7^(2x + 3) so that it is unambiguous.

And, to be unambiguous, type "7^(x^2)"
