Answer 2

Explicație pas cu pas:

$(( - 7) \times 3 + ( - 2) \times ( - 5) - (3^{2} ) \times ( - 5) {}^{2} ) \div ( - 2 {}^{2} ) \\ ( - 21 + ( - 2) \times ( - 5) - ( - 3 {}^{2} \times (5) {}^{2} ) \div ( - 2 {}^{2} ) \\ ( - 11 + 3 {}^{2} \times 5 {}^{2} ) \div ( - 2 {}^{2} ) \\ \frac{ - 11 + 15 {}^{2} }{ - 2 { }^{2} } \\ \frac{ - 11 + 225}{2 {}^{2} } \\ \frac{214}{ - 4} \\ \frac {107}{ - 2}$
