Question

60÷{2x[-7+18÷(-3+12)]}-[7x(-3)-18÷(-2)+1]

Answer 1

Olá,

Vamos lá,

= 60÷{2x[-7+18÷(-3+12)]}-[7x(-3)-18÷(-2)+1]
= 60÷{2x[-7+18÷9]}-[7x(-3)-18÷-2+1]
= 60÷{2x[-7+2]}-[-21+9+1]
= 60÷{2x[-5]}-[-11]
= 60÷{ -10}+11
= - 6 + 11
= 5

Answer 2

Olá,

Vamos lá,

= 60÷{2x[-7+18÷(-3+12)]}-[7x(-3)-18÷(-2)+1]

= 60÷{2x[-7+18÷9]}-[7x(-3)-18÷-2+1]

= 60÷{2x[-7+2]}-[-21+9+1]

= 60÷{2x[-5]}-[-11]

= 60÷{ -10}+11

= - 6 + 11

= 5
