a) 64 - 4 x 6 - 48
= 4 x 16 - 4 x 6 - 48
= 4 x (16 - 6) - 48
= 4 x 10 - 48
= 40 - 48
= -8
b) 96 - 32 : 4 - 49
= 96 - 8 - 49
= 39
Tính
a )
64 - 4 x 6 - 48
= 64 - 24 - 48
= 40 - 48
= -8
b )
96 - 32 : 4 - 49
= 96 - 8 - 49
= 88- 49
=39
tk mk nha
mơn nhiều ạ
a) 64-4x6-48
=4x16-4x6-48
=4x(16-6) - 48
=4 x 10 - 48
=40-48
=8
b)96-32:4-49
=96-8-49
=39
64 - 4 x 6 - 48
= 4 x 16 - 4x 6 -48
= 4 x ( 16 - 6 ) -48
= 40 - 48 = - 8
96 - 32 : 4 -49
= 96 - 8 - 49
= 39
64-4*6-48
=4*16-4*6-48
=4*(16-6)-48
=4*10-48
=40-48
=-8
