Объяснение:

$( \frac{ {76}^{3} - {44}^{3} }{32} + 76 \times 44) \div ( {130}^{2} - {50}^{2} ) = ( \frac{(76 - 44)( {76}^{2} + 76 \times 44 + {44}^{2} )}{32} + 76 \times 44) \div ((130 - 50)(130 + 50) )= ( {76}^{2} + 76 \times 44 + {44}^{2} + 76 \times 44) \div (80 \times 180 )= ( {76}^{2} + 2 \times 76 \times 44 + {44}^{2} ) \div (80 \times 180 )= \frac{ {(76 + 44)}^{2} }{80 \times 180} = \frac{ {120}^{2} }{20 \times {2}^{2} \times 60 \times3 } = \frac{ {60}^{2} \times {2}^{2} }{20 \times {2}^{2} \times 60 \times3 } = \frac{60}{20 \times 3} = \frac{60}{60} = 1$
