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
===============================

^{-1/3} = -1)
Negative exponents signify the reciprocal and fractional exponents signify roots, so the following is an equivalent equation:
Just raise each side to the 3rd power:
Multiply both sides by x + 3:
=========================================================
^3 = 5^3 = 125)
=========================================================
Add -2 to both sides:
Square both sides:
Add -(1 - 8x) to both sides:
Factor:
(x + 3) = 0)
