Question

[-7)×3+(-2)×(-5)-(-3)²×(5)²]÷(-2²) (URGENT !!!!)

Answer 1

$( - 7 \times 3 + ( - 2) \times ( - 5) - {( - 3)}^{2} \times {(5)}^{2} ) \div ( { - 2}^{2} ) = \\ = ( - 21 + 10 - 9 \times 25) \div 4 \\ = ( - 11 - 225) \div 4 = - 236 \div 4 \\ = - 59$

Answer 2

Răspuns:

daca ii [(-7)×3+(-2)×(-5)-(-3)²×(5)²]÷(-2²) atunci raspunsul ii 59

Explicație pas cu pas:

={-21+10-[(-3)x5]patrat} : (-2patrat)=

=[-11-(-15patrat]:(-2patrat)=

=(-11-15patrat):(-2patrat)=

=-11-15patrat/-2patrat=

=-11-225/-4=

=-236/-4= 59

scz ca n-am putut scrie patrat normal
