Find the constant rate first, then the start point (-1,3) (3,-5)

You need to use these two rules of exponents:
To raise a product to a power, raise each factor to the power.
To raise a power to a power, multiply the powers.

The product inside the parentheses is being raised to the power 1/2.
Raise each factor to the power 1/2.





Now multiply the exponents.



Finally, use the definition of a rational exponent to change the exponent of x into a root.
