How can we solve these type of problems:

e.g. $2^{x}=x$

or, $2^{x}=x^{2}$

To find the possible value(s) of x.

Try using graphs and apply calculus. · 1 year, 11 months ago

thanks. I'll try that way. · 1 year, 11 months ago

Use logarithm too. That will make the problem easier. · 1 year, 11 months ago
