Chúc bn học tốt
\(54\times\left(46+49\right)-46\times\left(54-49\right)\)
\(=54\times46+54\times49-46\times54+46\times49\)
\(=\left(54\times46-46\times54\right)+49\times\left(54+46\right)\)

a. 4.37.25.50.12
=(4.25).(50.12).37
=100.600.37
=2220000
\(a.\left(4.50\right).\left(25.12\right).37\)
\(=200.300.37=2220000\)
\(b.\left(46+54\right)+\left(17+83\right)\)
\(=100+100=200\)
\(c.87.\left(36+69\right)=87.105=9135\)
\(d.\left(135+65\right)+\left(360+40\right)\)
\(=200+400=600\)
\(e.\left(463+137\right)+\left(318+22\right)\)
\(=600+340=940\)
Ta có:
46 + 17 + 54 = ( 46 + 54 ) + 17 = 100 + 17 = 117
