Solved given expression for x using the change of base formula log base b of y equals log y over log b is 1.46497

Step-by-step explanation:

Given Expression:

To solve this, first convert the exponential form into log form

If

So, when comparing the given expression with above,  a = 3, x = x + 1 and b = 15.

become as

Now, apply change of base formula to remove base 3 ,

Hence,

Substitute in above expression, we get

    x + 1 = 2.46497

    x = 2.46497 - 1

    x = 1.46497
