# Math Help - solving for x

1. ## solving for x

Hi! My problem is:

(x)(2^x) = 1

How do I solve for x? I tried using logarithms like this:

log(x) + x*log(2) = log(1)

but then I have the first x stuck inside a log. Help please!

2. What you have tried is not correct.

You cannot solve this using conventional algebra.

You should try a numerical method.

I get $x\approx 0.64$

3. Do you mean I should just use my graphing calculator? I get about the same when I do that. Just out of curiosity, what kind of algebra would you use to do this?

4. The conventional algebra I speak of is using inverse operations to isolate x.

The other types of algebra (i.e. abstract algebra) aren't related to achieving this result.

5. OK, thanks!
