16. Square Roots and nth roots When c≥0, the square root of c is the non negative solution of the equation x 2 =c Cube roots, fourth roots, and higher roots are defined as solutions of the equation x n =c These equations can be solve graphically by finding the x coordinate of the intersection points of y=x n and y=c
