What is exponential form?
The exponential form is a way of writing numbers using bases and powers. It tells us how many times we actually multiplying a number to get the result.
log1010000 = z
a = 10
b = 10000
c = z
Here a,b,c can be written as per the given formula
b = ac(formula)
10000 = z
10000 = z
So it is 10000 = z
