 Question 96205: Please help me solve this problem: y^4/3 = -3y This is what I have done: y^4/3 + 3y =0 1. The exp of y is understood to be 1...so does this mean that I need to find the commoon denominator of the exp so that I could add? Should the exp of 3y then be 1/3? y^4/3 + 3y^1/3= 0 2. Then in the book it says to factor out maybe 1/3? This is where I get confused, because the problem in the book that is simmilar looks like this: x^3/2= x^1/2 x^3/2- x^1/2= 0 x^1/2(x-1)) =0 How are they factoring out x^1/2? Is x^1/2(x-1) = x^3/2 -x^1/2 3. So once they get x^1/2= 0 and x-1=0 so the answer is x=0 and x=1 Click here to see answer by stanbon(57410)

 Question 96379: square root(2x-9)= 1/3 The first thing I did was square both sides to get rid of the radical. This leaves: 2x-9 = 1/9 Am I supposed to add nine to both sides? When I tried to do this I ended up with this: 2x= 1/9+ 9 2x= 1/9+ 9/1 2x = 1/9+ 81/9 2x= 82/9 1. This doesn't seem right. How do I get rid of the 2? Click here to see answer by edjones(7569)
