In Exercises 51-52 of Section 2.5, algebraic methods were used to find solutions to each of the following equations. Now solve the equation graphically by assigning the expression on the left side to Y1 and the number on the right side to Y2 and then finding the x-coordinates of all points of intersection of the two graphs.
(a) x5/3 = 32
(b) x4/3 = 16
(c) x2/3 = −36
(d) x3/4 = 125
(e) x3/2 = −27
Exercise 51
Find the real solutions of the equation.
(a) x5/3 = 3
(b) x4/3 = 16
(c) x2/3 = −36
(d) x3/4 = 125
(e) x3/2 = −27
Exercise 52
Find the real solutions of the equation.
(a) x3/2 = −27
(b) x2/3 = 25
(c) x4/3 = −49
(d) x3/2 = 27
(e) x3/4 = −8
