f(x)=(4x)/(~(x^(2)))+15
Pull all perfect square roots out from under the radical. In this case, remove the x because it is a perfect square.
f(x)=(4x)/(x)+15
Arrange the variables alphabetically within the expression (4x)/(x). This is the standard way of writing an expression.
f(x)=(4x)/(x^(0))+15
Any variable raised to the power of 0 is 1.
f(x)=4x+15
