9/4 x ^1/2

Why do you have to flip it to 2/3?

5. phi

if you fix up the coefficient to 2/3 (instead of 3/2) it will work the formula $\int x^n = \frac{1}{n+1}x^{n+1}$ if n+1 is a fraction, dividing is the same as flipping it

$\int\limits_{}^{}x^\frac{ 1 }{ 2 } = \frac{ 3 }{ 2 }x ^{\frac{ 1 }{ 2 }+1}$

@phi Thanks I understand now, forgot It was 1/ the n+1

8. phi

for example $\frac{1}{\frac{3}{2} } = \frac{1 \cdot \frac{2}{3}} {\frac{3}{2} \cdot \frac{2}{3}}$ ant that is $\frac{ \frac{2}{3}}{1} = \frac{2}{3}$
