Answer:
Exponential form: y = x^½
Step-by-step explanation:
Given

Required:
The exponential form
To convert to an exponential function, we have to take exponents of both sides using the base of the logarithm function.
This gives us

Since the base of the exponential function and the logarithm is the same (x), they'll cancel out one another
This leaves us with

Hence, the exponential form of the expression
is
