1. ## Advanced Logarithm problem ::HELP::

The problem is easy: X^2=2ln(X+2) Solve graphically and the answer comes out to be 1.6007 [rounded]

Our teacher challenged us to solve it ALGEBRAICALLY...he doesnt know if it is possible or but he wants us to find out and will give us extra credit if we get the steps on how to do it....

Challenge:

X^2=2ln(X+2) Solve Algebraically

2. I am not ashamed to say I don't know to do it because all I have done in the past was numerically or graphically. You can't isolate the x, and even if you set a power series equal to ln(x) or exp(x) it will be to complex to solve without a computer.

There is no way to solve this algebraically. I would suggest a binary search might be a good way to find a solution. I get $\displaystyle x \approx 1.60071 \text{ and } x \approx -0.711744$
