Question

(-5)³×{396-720÷[-7+(6590+51×210)÷(-2²×5²)]}

va rog redede,dau coroana ​

Answer 1

Explicație pas cu pas:

${( - 5)}^{3} \times \{396 - 720 \div \left[ - 7 + (6590 + 51 \times 210) \div ( - {2}^{2} \times {5}^{2}) \right]  \} =$

$= ( - 125) \times \{396 - 720 \div \left[ - 7 + (6590 + 10710) \div ( - 4 \times 25) \right]  \}$

$= ( - 125) \times \{396 - 720 \div \left[ - 7 + 17300 \div ( - 100) \right]  \}$

$= ( - 125) \times \{396 - 720 \div \left[ - 7 - 173 \right]  \}$

$= ( - 125) \times \{396 - 720 \div ( - 180) \}$

$= ( - 125) \times (396 + 4)$

$= ( - 125) \times 400$

$= - 50000$

Answer 2

Răspuns:

(-5)³×{396-720÷[-7+(6590+51×210)÷(-2²×5²)]}=

-125×{396-720÷[-7+(6590+10710)÷(-4×25)]}=

-125×{396-720÷[-7+17300÷(-100)]}=

-125×{396-720÷[-7+(-173)]}=

-125×[396-720÷(-180)]=

-125×(396+4)=

-125×400=

-50000
