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

x= 1.46497

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

The value of x is 1.46.

Step-by-step explanation:

Given : Equation

To find : Solve for x using the change of base formula log base b of y equals log y over log b ?

Solution :

Equation

Applying the logarithmic property,

Applying change base formula in LHS,

Therefore, the value of x is 1.46.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

this is a good question! i'll do some research and come back when i have the answer!
