Trên tia Ox lấy hai điểm M, N sao cho ON = 7 cm, OM = 3 cm. Gọi điểm A là trung điểm của MN . Tính độ dài đoạn thẳng OA.
Giúp em với ạ, em cảm ơn.
Vì điểm M nằm giữa 2 điểm O và N nên ta có:
⇔ OM + MN = ON
Thay số : 3 + MN = 7
MN = 7 - 3
⇔ MN= 4 cm.
Vì A là trung điểm của MN nên ta có:
⇔ MA = AN = MN/2
Thay số : MA = AN = 4/2 = 2cm
⇔ Điểm M nằm giữa 2 điểm O và A nên ta có:
⇔ OM + MA = OA
Thay số : 3 + 2 = OA
⇔ OA = 5cm.
Vậy OA = 5cm.
Mọi người giúp em với ạ chiều nay em phải nộp rồi ạ. Em xin cảm ơn ạ.

\(a^3b-ab^3=ab\left(a^2-b^2\right)=ab\left(a^2-ab+ab-b^2\right)=ab\left(a-b\right)\left(a+b\right)\)
Với a hoặc b chẵn \(\Leftrightarrow ab\left(a-b\right)\left(a+b\right)⋮2\)
Với a và b lẻ \(\Leftrightarrow\left(a-b\right)⋮2\Leftrightarrow ab\left(a-b\right)\left(a+b\right)⋮2\)
Vậy \(ab\left(a-b\right)\left(a+b\right)⋮2,\forall a,b\left(1\right)\)
Với a hoặc b chia hết cho 3 thì \(ab\left(a-b\right)\left(a+b\right)⋮3\)
Với \(a=3k+1;b=3q+1\Leftrightarrow\left(a-b\right)=3\left(k-q\right)⋮3\)
\(\Leftrightarrow ab\left(a-b\right)\left(a+b\right)⋮3\)
Với \(a=3k+1;b=3q+2\Leftrightarrow\left(a+b\right)=\left(3k+1+3q+2\right)=3\left(k+q+1\right)⋮3\)
\(\Leftrightarrow ab\left(a-b\right)\left(a+b\right)⋮3\)
Mà a,b có vai trò tương đương nên \(ab\left(a-b\right)\left(a+b\right)⋮3,\forall a,b\left(2\right)\)
\(\left(1\right)\left(2\right)\Leftrightarrowđpcm\)
Ta có : a3b -ab3
=a3b -ab -ab3 +ab
=ab (a2 -1) -ab (b2 -1)
=ab (a-1)(a+1) -ab (b-1)(b+1)
Vì a (a-1)(a+1) là 3 số tự nhiên liên tiếp nên chia hết cho 6 .Tương tự b (b-1)(b+1) cũng chia hết cho 6
=> a3b -ab3 chia hết cho 6 (đpcm )
