27 x 31 + 31 x 73
= 31 x ( 27 x 73 )
= 31 x 100
= 3100
16 x 98 + 16 x 2
= 16 x ( 98 + 2 )
= 16 x 100
= 1600
31*(27+73)=31*100=3100
16*(98+2)=16*100=1600
k mik
27 x 31 + 31 x 73
=31x(27+73)
=31x100
=3100
16x98+16x2
=16x(98+2)
=16x100
=1600
tk nha bạn
thank you bạn
(^_^)
27 x 31 + 31 x 73
= 31 x ( 27 + 73)
= 31 x 100
= 3100
16 x 98 + 16 x 2
= 16 x ( 98 + 2)
= 16 x 100
= 1600
31 + < 27 * 73 >
= 31 + 1971
= 2002
16 * < 98 + 2 >
=16 * 100
1600
a) 27x31+31x73
= 31x(27 + 73)
= 31x100
= 3100
b) 16x98 + 16x2
= 16x(98+2)
= 16x100
= 1600
27 x 31 + 31 x 73
= 31 ( 27 + 73 )
= 31 * 100
= 3100
16 x 98 + 16 x 2
= 16 ( 98 + 2 )
= 16 * 100
= 1600
k mk nha
