de preferencia com todo o calculo

Answer 1

A) 4x-[3x-(4-x)]+5x-6=
4x-[3x-4+x]+5x-6
4x-3x+4+x+5x-6
4x-3x+x-6+4=
2x-2

B) 4m²+3m-[5m-(3m²-2)+2m-(m²-3)]
4m²+3m-[5m-3m²+2+2m-m²+3]
4m²+3m²-5m+3m²-2-2m+m²-3
4m²+3m²+m²+3m-5m-2m-2-3=
8m²-4m-5

C) -3a²b³+5a³b²- {-a³b²-2a²b³-[4a³b²-(8a²b³-7a³b²)-a²b³]-3a³b²}
-3a²b³+5a³b²-{-a³b²-2a²b³-[4a³b²-8a²b³+7a³b²-a²b³]-3a³b²}
-3a²b³+5a³b²-{-a³b²-2a²b³-4a³b²+8a²b³-7a³b²+a²b³-3a³b²}
-3a²b³+5a³b²+a³b²+2a²b³+4a³b²-8a²b³+7a³b²-a²b³+3a³b²
-3a²b³+2a²b³-8a²b³-a²b³+5a³b²+a³b²+4a³b²+7a³b²+3a³b²=
-10a²b³+20a³b²

D) -3m²+5mp-p²-{-m²-2mp-[4m²-mp-3p²-(4m²-7p²)+2mp-(m²-6mp)]}
-3m²+5mp-p²-{-m²-2mp-[4m²-mp-3p²-4m²+7p²+2mp-m²+6mp]}
-3m²+5mp-p²-{-m²-2mp-4m²+mp+3p²+4m²-7p²-2mp+m²-6mp}
-3m²+5mp-p²+m²+2mp+4m²-mp-3p²-4m²+7p²+2mp-m²+6mp
-3m²+m²+4m²-4m²-m²+5mp+2mp-mp+2mp+6mp-p²-3p²+7p²=
-3m²+14mp²+3p²
