How to solve the equation 2^x=19

Question

I don't know where to begin

Answer 1

Hi Jarrett,

 

You will have to apply logarithms of base 2 to both sides. That gives you:

 

x = log(19) / log(2)   Both logarithms are now in base 10, by the change of base formula.

 

x ≈ 4.25

 

Hope this helps!
