A square root is a number raised to the exponent (power) 1/2.
The coefficient is the number placed before a variable, or variables. As for the exponent: taking the square root of a number is the same as raising it to the power 1/2, so you can consider the exponent to be 1/2. Edit: So coefficient is ./3 and exponent is 1/2
And exponent of -2 represents the square root
The square of a number can be represented by writing the number with an exponent of 2, whereas the square root of the number is represented by writing the number with an exponent of 1/2.
That means that the exponent is a fraction, such as 21/2 = square root of 2, 101/3 = cubic root of 10, etc.
