Hello,

I need a clue/hint in solving this exponential function

Here is a Hint/Clue for you....

Multiply the equaiton by $3^x$ to get

$(3^x)^2+1(3^x)+56=0$

This is quadratic in $3^x$ so let $u=3^x$...

Good luck

3. I think there may be a typo otherwise it will not have any solutions.

Maybe

$3^x+1-56(3^{-x})=0$

If this is the case use the same hint.
