\(180+450\div5\times3-210.\)
Ta sẽ thêm ngoặc đơn như sau:
\(\left[180+450\div\left(5\times3\right)\right]-210\)
\(=\left[180+450\div15\right]-210\)
\(=\left[180+30\right]-210\)
\(=210-210\)
\(=0\)
180 + 450 :5 x3 - 210
=180 + 450 :( 5 x 3) - 210
=180+450 :15 -210
=180 + 30 - 210
=210 - 210
=0
180+450÷5×3-210
180+450÷(5×3)-210=180+450÷15-210
=180+30-210
=210-210
=0
k cho mình đi
180+450÷5×3-210
180+450÷(3×5)-210
=180+450÷15-210
=180+30-210
=210-210
=0
Chọn mìn nhaaaa
đáp án là \(180+450\div\left(5\text{x}3\right)-210=0\)
Đặt A=180+450:5.3-210
=> A=[180+450:(5.3)]-210
=> A=[180+450:15]-210
=> A=[180+30]-210
=> A=210-210
=> A=0 (đ p c m)
K mình nhé!
Đặt A= 180+450:5.3-210
=> A=(180+450:(5.3))-210
=>A=(180+450:15)-210
=>A=(180+30)-210
=>A=210-210
=>A=0
K mình nhé!
180+450:5.3-210
=180+450:(5.3)-210
=(180+30)-210
=210-210
=0
K mình nhé!
180+450:5.3-210
=180+450:(5.3)-210
=(180+30)-210
=210-210
=0
K mình nhé!
180 + 450 : 5 x 3 - 210
= 180 + 450 : ( 5 x 3 ) - 210
= 0
180 + 450 : 5 x 3 - 210
= 180 + 450 : ( 5 x 3 ) - 210
= 180 + ( 450 : 15 ) - 210
= ( 180 + 30 ) - 210
= 210 - 210
= 0
180 + 450 ÷ 5 x 3 - 210
= 180 + 450 : ( 5 x 3 ) - 210
= 180 + ( 450 : 15 ) - 210
= ( 180 + 30 ) - 210
= 210 - 210
= 0
Ta có: 180+450:5.3-210
=180+(450:5).3-210
=180+(130.3)-210
=180+290-210
=470-210
=260
Chú ý để hiểu nhá:Dấu chấm kia là dấu nhân(.)
Chúc bạn thành công
180 + 450 : (5 x 3) - 210
= 180 + 450 : 15 - 210
= 180 + 30 - 210
= 210 - 210
= 0
180 + 450 : (5 x 3) - 210
= 180 + 450 : 15 - 210
= 180 + 30 - 210
= 210 - 210
= 0
180+450:5.3-210
=180+450:(5.3)-210
=180+30-210
=210-210
=0.
