a)
\(357\times46+357\times54\)
\(=357\times\left(46+54\right)\)
\(=357\times100\)
\(=35700\)
b)
\(246\times78-246\times68\)
\(=246\times\left(78-68\right)\)
\(=246\times10\)
\(=2460\)
a) 357x46+357x54
=357x(46+54)
=357x100
=35700
b) 246x78-246x68
=246x(78-68)
=246x10
=2460
a ) 375 * 46 + 357 * 54
=357 * ( 46 + 54 )
= 357 * 100
= 35 700
b ) 246 * 78 - 246 * 68
= 246 * ( 78 - 68 )
= 246 * 10
= 2 460
Tích mik nha!
Mik đã giúp bn rùi
a) 357 * ( 46+54) = 357 * 100=35700
b) 246*(78-68) = 246*10=2460
a) \(357.46+357.54\)
\(=357.\left(46+54\right)\)
\(=357.100\)
\(=35700\)
b) \(246.78-246.68\)
\(=246.\left(78-68\right)\)
\(=246.10\)
\(=2460\)
a) \(357.46+357.54=357.\left(46+54\right)=357.100=35700\)
b) \(246.78-246.68=246.\left(78-68\right)=246.10=2460\)
