What is exponential form?
The exponential form is a way of writing numbers using bases and powers. It tells us how many times are we actually multiplying a number to get the result.
log5 25 = 2
a = 5
b = 25
c =2
Here a,b,c can be written as per the given formula
b = ac(formula)
25 = 2
So it is 25 = 2
