Answer 2

The solution of the logarithmic equation is approximately 5.66 .

The logarithm is a simpler way to write a exponential equation.

The exponential equation nˣ = b is written as logₙ b=x( read as logarithm of b to the base of n is equal to x).

The various properties of logarithm are:

log x+ log y= log xylog x - log y= log(x/y)log xⁿ=n log xlogₐᵃ=1

The given equation is :

log₂ x = 2.5

This equation is of the form logₐ b=n

We know that from the properties of logarithm logₐ b=n is equivalent to aⁿ=b.

So the given equation can be written as

Solving we get

x=5.6568....

or, x≈5.66

Therefore the logarithm equation has a solution for x where the value of x is approximately 5.66.
