Answer 2

K)[450:5:(3x6)+35]x7-140+(540:6+7)x(63:9)
=(450:5:18+35)x7-140+97x7
=40x7-140+97x7
=280-140+679
=140+679
=819
L)[500-(3500:700x80-40x9)x(64:8)]:9-(72:6):(81:27)
=[500-(5x80-360)x8]:9-12:3
=(500-40x8):5
=(500-320):5
=180:5
=36
M)2x{350:[491-3x(125-78)]+350}
=2x[350:(491-3x47)+350]
=2x[(350:350)+350]
=2x(1+350)
=2x351
=702
Sper ca te-am ajutat,coroana?
