17 x 19 + 17 x 81
=17 x ( 19 + 81 )
= 17 x 100
= 1700
17 x 19 + 17 x 81
= 17 x ( 19 + 81 )
= 17 x 100
= 1700
17 x 19 + 17 x 81 = 17 x ( 19 + 81 ) = 17 x 100 = 1700
17 x 19 + 17 x 81
= 17 x ( 19 + 81 )
= 17 x 100
= 1700
\(17\times19+17\times81\)
\(=17\times\left(19+81\right)\)
\(=17\times100\)
\(=1700\)
\(17\cdot19+17\cdot81\)
\(=17\left(19+81\right)\)
\(=17\cdot100\)
\(=1700\)
17 x 19 + 17 x 81
= 17 x ( 19 + 81 )
= 17 x 100
= 1700
Ta có: 17 x 19 + 17 x 81
= 17 x ( 19 + 81 )
= 17 x 100
= 1700
17 x 19 + 17 x 81
= 17 x ( 19 + 81 )
= 17 x 100
= 1700
