solve:
2 ln e= ln sqrt of 7/x2 ln e
what would be x?

math 
Steve,
Assuming parentheses as shown below, and recalling that ln(e) = 1,
2 ln e= ln sqrt(7/(x2)) ln e
2 = ln √(7/(x2))
√7/(x2)) = e^2
7/(x2) = e^4
x2 = 7e^4
x = 2 + 7e^4

Thanks Steve I have it now, But the answer checked out to be e^4+ln sqrt 7
