If you write
![y=x^{1/3}](https://tex.z-dn.net/?f=y%3Dx%5E%7B1%2F3%7D)
, you'll notice this is really just a quadratic equation that can be factorized:
![2x^{2/3}+3x^{1/3}-5=0\iff 2y^2+3y-5=0\iff (2y+5)(y-1)=0\iff(2x^{1/3}+5)(x^{1/3}-1)=0](https://tex.z-dn.net/?f=2x%5E%7B2%2F3%7D%2B3x%5E%7B1%2F3%7D-5%3D0%5Ciff%202y%5E2%2B3y-5%3D0%5Ciff%20%282y%2B5%29%28y-1%29%3D0%5Ciff%282x%5E%7B1%2F3%7D%2B5%29%28x%5E%7B1%2F3%7D-1%29%3D0)
So you have
![2x^{1/3}+5=0\implies 2x^{1/3}=-5\implies x^{1/3}=-\dfrac52\implies x=-\dfrac{125}8](https://tex.z-dn.net/?f=2x%5E%7B1%2F3%7D%2B5%3D0%5Cimplies%202x%5E%7B1%2F3%7D%3D-5%5Cimplies%20x%5E%7B1%2F3%7D%3D-%5Cdfrac52%5Cimplies%20x%3D-%5Cdfrac%7B125%7D8)

Answer:
the answer is 101/9, in fraction it would be 11.2222..... in whole number would be 11, as mixed number would be 11 2/9
Answer:
140
Step-by-step explanation:
first you take the product of 5/6 and 42/1, which is 210/6.
Then you devide that with 5, 210/6/5 = 210/30 or 210/6 . 1/5 = 70.
Next you multiply that with 2; 70 . 2 = 140.
There you go
