- 4 = r^{20} - 5

r = 1, r = - 1

Solution steps

- 4 = r^{20} - 5

Switch sides

r^{20} - 5 = - 4

Move

5

to the right side

r^{20} = 1

For

x^{n} = f (a)

, n is even, the solutions are

r = 1, r = - 1

3 x^{3} + 375 = 0

x = 6.9 + 9 (x - 5)^{3}

7 x^{3} + 3 x^{2} - 29 x + 11 = 0

- x^{3} + 5 x^{2} - 4 x = 0

x^{3} - 12 x^{2} - 56 x + 552 = 0
