Answer:500

step by step explanation:

$\frac{ {361}^{3} + {139}^{3} }{ {361}^{2} - (361 \times 139) + {139}^{2} } = \frac{(361 + 139)( {361}^{2} - (361 \times 139) + {139}^{2}) }{ {262}^{2} - (361 - 139) + {139}^{2} } \\ since \: \: a ^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} ) \\ answer = 361 + 139 = 500$
