Answer 1

( 30 - 5 x 6 ) : ( 7 + 2 x 10 ) x ( 40 - 30 + 5 )

( 30 - 30 ) : ( 7 + 20 ) x 15

0 : 27 x 15

0 : 405 = 0

Olá, bom dia ☺

Resolução:

$\\ (30-5\times6)\div(7+2\times10)\times(40-30+5) \\(30-30) \div(7+20) \times (40-25) \\0 \div ( 27)\times (15) \\ 0 \div 405 \\ \boxed{=0}$

Bons estudos :)
