50 + 50 + 90 + 10 + 55 + 45
= ( 50 + 50 ) + ( 90 + 10 ) + ( 55 + 45 )
= 100 x 3
= 300
nha bn
\(50+50+90+10+55+45\)
\(=\left(50+50\right)+\left(90+10\right)+\left(55+45\right)\)
\(=100+100+100\)
\(=100.3\)
\(=300\)
ko noi xao
nhae
50 + 50 + 90 + 10 + 55 + 45 = 100 + 100 + 100
= 300. hết lượt k bạn rồi nhưng vẫn trả lời lấy hên
50 + 50 + 90 + 10 + 55 + 45
= ( 50 + 50 ) + ( 90 + 10 ) + ( 55 + 45 )
= 100 + 100 + 100
= 100 x 3
= 300
nhé !
50+50+90+10+55+45
=(50+50)+(90+10)+(55+45)
=100+100+100
=100x3
=300
50+50+90+10+55+45
=(50+50) + (90+10) + (55+45)
=100+100+100
=100x3
=300
tk nhé
50 + 50 + 90 + 10 + 55 + 45
= ( 50 + 50 + ( 90 + 10 ) + ( 55 + 45 )
= 100 + 100 + 100
= 300
