Solution

The correct option is D $31$
$x = 2$
$∴ x^{2} = 4$
$y = 3$
$∴ y^{3} = 27$
$∴ x^{2} + y^{3} = 4 + 27 = 31$

Q. If x + y = 3 and xy = 2, then the value of

x^{3} - y^{3}

x^{2} = y^{3}

then prove that

{(\frac{x}{y})}^{\frac{3}{2}} + {(\frac{y}{x})}^{\frac{2}{3}} = x^{\frac{1}{2}} + y^{- \frac{1}{3}}

x + y = 5, x^{3} + y^{3} = 35
