How to Solve the Logarithm Equation?

Follow the simple guidelines on how to solve the Logarithm Equation manually by hand. They are along the lines

If we are given the equation logbx =y → (1)

The following is also true b logbx = by → (2)

Use the Logarithmic Function x = blogbx

Rewriting Equation 2 we get the following one

x = by → (3)

Solving the value of b in equation 3 we get

b = y√x

Solve for the value of y in equation 3 we get

x = by

Taking logarithm on both sides we get

log10 x = log10by

Applying Logarithmic Identities and rewriting the equation we get the following

log10 x = y. log10 b

Divide both the sides of the equation with log b

y = (log10 x)/log10b)

= log x/log b

Do remember writing log without the subscript, in general, is assumed to be log based 10.

Question: Solve for b in the logarithmic equation logb 8 = 2?


Given logb 8 = 2

We know the given equation is the same as b logb 8 = b2

Applying Logarithmic Function and rewriting the equation we get as such

8 = b2

Taking the Square root of 8 to find the b value we get

b = 2√8

= 2. √4.2

= 2.2.√2

= 4√2
