Well, if 24 is 4% of a number, then you need to work out what 100% is. The formula is 100/4 i.e. 100% divided by 4%= 25 25 x 24 = 600

$2x^{2/3}+3x^{1/3}-2=(2x^{1/3}-1)(x^{1/3}+2)=0$

Then

$2x^{1/3}-1=0\implies2x^{1/3}=1\implies x^{1/3}=\dfrac12\implies x=\dfrac18$

$x^{1/3}+2=0\implies x^{1/3}=-2\implies x=-8$

(assuming you are solving over the real numbers)
