Question 179117
26) (x + 3)^-1/3 = -1
Raise both sides to the -3 power to get:
x+3 = -1
x = -4
------------------- 
24) 25^3/2 = 5^3 = 125
----------------------------------
22) x = SR(1-8x) + 2
SR(1-8x) = x-2
Square both sides to get:
1-8x = x^2 -4x + 4
x^2 + 4x  +3 = 0
(x+1)(x+3) = 0
x = -1 or x = -3
