HEY GUYS,

I'm working my way through an online course and it is impossible getting a phone call back from my teachers. This equation has been bothering me for days now and its holding me back.

4(2^x)+31(2^x)-8=0

The lesson i'm on is exponential and logarithmic equations, and i understand i'm supposed to find common bases' and apply logarithms, but for some reason this question is beyond me. Any help in the right direction would be much appreciated. THANKS
