64 × 23 + 37 × 23 - 23
= 23 × ( 64 + 37 - 1 )
= 23 × 100
= 2300
64.23+37.23-23
=(64-+37-1).23
=100.23
=2300
64 x 23 + 37 x 23 - 23 = 64 x 23 + 37 x 23 - 23 x 1
= ( 64 +37 - 1 ) x 23
= 100 x 23
= 2300
nhớ k mk nha
64 . 23 + 37 . 23 - 23
= 23 ( 64 + 37 - 1 )
= 23 . 100
= 2300
\(64\times23+37\times23-23\)
\(=23\times\left(64+37-1\right)\)
\(=23\times100\)
\(=2300\)
64 . 23 + 37 . 23 - 23
= 23 ( 64 + 37 - 1 )
= 23 . 100
= 2300
64 x 23 + 37 x 23 -23
= 23 x ( 64 + 37 - 1 )
= 23 x 100
= 2300
64 . 23 + 37 . 23 - 23
= 23 . ( 64 + 37 - 1 )
= 23 . 100
= 2300
64x23+37x23-23
=23x(64+37-1)
=23x100
=2300
64 x 23 + 37 x 23 - 23
= 23 x ( 64 + 37 - 1 )
= 23 x 100
= 2300
