Question

7.m².n+10:m.n²-5m³.n³, para m=5 e n=3.​

Answer 1

Explicação passo-a-passo:

$7 \times {m}^{2} \times n + 10 \div m \times { n}^{2} - 5 {m}^{3} \times {n}^{3} \\ 7 \times {5}^{2} \times 3 + 10 \div 5 \times {3}^{2} - 5 \times {5}^{3} \times {3}^{3} \\ 7 \times {5}^{2} \times 3 + 2 \times {3}^{2} - 5 \times {5}^{3} \times {3}^{3} \\ 3(7 \times {5}^{2} + 2 \times 3 - 5 \times {5}^{3} \times {3}^{3} \\ 3(7 \times 25 + 6 - 5 \times {5}^{3} \times 9) \\ 3(175 + 6 - 9 \times {5}^{4} ) \\ 3(181 - 9 \times 625) \\ 3(181 - 5625) \\ 3 \times ( - 5444) \\ - 16332$
