The lesson in my intermediate algebra math class is radical expressions. The problem I am having trouble on is (4y+1)^1/3 = -1
So far I understand that the fraction exponent is actually a cube root and for some reason, I keep getting y = -2/4

The lesson in my intermediate algebra math class is radical expressions. The problem I am having trouble on is (4y+1)^1/3 = -1
So far I understand that the fraction exponent is actually a cube root and for some reason, I keep getting y = -2/4

anonymous · Answer

if the cubed root is -1, then the whole thing is -1, i.e 
$$4y+1=-1$$

anonymous · Answer

if you keep getting $-\frac{2}{4}$ that is good, but you might want to write it as $-\frac{1}{2}$

Oh, okay. The thing is my teacher doesn't like fractions so I figured the answer shouldn't be a fraction. Thank you.
