70 x 70 : 70 + 80 : 2
= 4900 : 70 + 80 : 2
= 70 + 40
= 110
70 x 70 : 70 + 80 : 2
= 4900 : 70 + 40
= 70 + 40
= 110
Answer : 110
=4900:70+40
=70+40
=110
(50 kí tự)
70 x 70 : 70 + 80 : 2= 70 + 80 :2 =70 + 40 = 110
mik rồi bạn mik nha
110 nha bn
tích mk nha các bn
thanks
>_< học tốt
\(70\times70\div70+80\div2\)
\(=4900\div70+40\)
\(=70+40\)
\(=110\)
70 x 70 : 70 + 80 : 2
= 4900 : 70 + 40
= 70 + 40
= 110
Vậy nhé!
OK
70x70:70+80:2
=4900:70+80:2
=70+80:2
=70+40
=110
70 x 70 : 70 + 80 : 2
= 70 x ( 70 : 70 ) + 80 : 2
= 70 x 1 + 80 : 2
= 70 + 40
= 110
70x70:70+80:2
=70x(70:70)+80:2
=70x1+40
=110
70 × 70 ÷ 70 + 80 ÷ 2
= 70 + 40
= 110
Chúc bạn hok giỏi
