23 x 50 + 49 x 23 + 23
= 23 x 50 + 49 x 23 + 23 x 1
= 23 x ( 50 + 49 + 1 )
= 23 x 100
= 2300
23 x 50 + 49 x 23 + 23
= 1150 + 1129 + 23
= 2302
23 x 50 + 49 x 23 + 23
= 23 x ( 50 + 49 + 1 )
= 23 x 100
= 2300
23 x ( 50 + 49 ) + 23
23 x 99 + 23
= 2277 + 23
= 2300
k mk nha!!
23 x 50 + 49 x 23 + 23
= 23 x ( 50 +49 + 1 )
= 23 x 100
= 2300
23x50+49x23+23
= 23 x( 50 + 49 + 1)
= 23 x 100
= 2300
\(23.50+49.23+23\)
\(=23.\left(50+49+1\right)\)
\(=23.100\)
\(=2300\)
T nha mik sẽ T lại
Bài kia mk nhầm nhé:
50 + 49 x 23 + 23
= 23 x 50 + 49 x 23 + 23 x 1
= 23 x ( 50 + 49 + 1 )
= 23 x 100
= 2300
23 x 50 + 49 x 23 + 23
= 23 x ( 50 + 49 + 1 )
= 23 x 100
= 2300
23 x 50 + 49 x 23 + 23
= 23 x ( 50 +49 + 1 )
= 23 x 100
= 2300
50 + 49 x 23 + 23
= 23 x 50 + 49 x 23 + 23 x 1
= 23 x 100
= 2300
