answered-by-expert Expert Answer

If three quantities a,x and n are related by the equation,

 a raised to x = n

 then x is said to be the logarithm of the number n to the base a.

In this a must be a positive real number which is not equal to 1.

If the base is not mentioned then it's taken to be 10.
