You can use radical notation or you can convert the expression to one with a rational exponent. There are two radical keys that you can use. These are demonstrated below. 1. Square Root Functions Enter the function by using the square root key and then enter it by using a rational exponent.The square root key is accessed by entering and then. This is shown as the function y1 below. To enter the function as a rational function, use the exponent 1/2.Remember to put the parentheses in.ou can use radical notation or you can convert the expression to one with a rational exponent.
