if I remember correctly, the log symbology

**lg**indicates a base 2 logarithm ... ?

... your work shows you are assuming it's a base 10 logarithm. - Jan 8th 2013, 01:19 AMshervladRe: Logarithmic equation, please help!
in the country I live in, lg means log base 10, but I solved it already so no problem any more, it was a mistake in the textbook, there should be 1.5logx not just 1.5x

Getting back to the original equation, because you have the unknown, x, as base

**and**in the exponent, there is not going to be any "algebraic" method. You might, with a lot of algebraic manipulation, get this into a form in which you could apply "Lambert's W function" (defined as the inverse function to ) but I don't see any simple way to do that.
