Question 141591: Please explain the steps to me for exponential functions. A example is 2^x=1.2+2.5
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
2^x=1.2+2.5
2^x=3.7
log[2](2^x)=log[2](3.7)
x=log[2](3.7) Inverse property
x=ln(3.7)/ln(2) change of base formula
x=1.88753
