Question

Solve 3^(x+1) = 15 for x using the change of base formula log base b of y equals log y over log b.

Answer 1

Step-by-step explanation:

To solve this , first we convert the exponential form in to log form

becomes

now we apply change of base formula to remove base 3

like that log_3(15) becomes

2.46497=x+1

subtract 1 from both sides

x= 1.46497
