Question

5x(4+3x7)-2x{5+2x[10-3x(14-3x4)]}

Answer 1

Explicație pas cu pas:

= 5(4 + 3 × 7) - 2(5 + 2(10 - 3 (14 - 3 × 4)))

= 5(4 + 21) - 2(5 + 2(10 - 3(14 - 12)))

= 5(25) - 2(5 + 2(10 - 3(2)))

= 5 × 25 - 2(5 + 2(10 - 3 × 2)))

= 125 - 2(5 + 2(10 - 6)))

= 125 - 2(5 + 2(4))

= 125 - 2(5 + 2 × 4)

= 125 - 2(5 + 8)

= 125 - 2(13)

= 125 - 26

= 99 ✓
