CÓ THẤY CÒN TẬP GÌ ĐÂU MÀ TẬP CON

Các tập hợp sau là các tập hợp nào vậy,mình ko thấy.

a) Trên đoạn thẳng AB, ta có: AM < AB (2cm < 6cm)

=> điểm M nằm giữa 2 điểm A và B

Ta có: AM + MB = AB

   =>   2     + MB = 6

   =>             MB = 6 - 2

   =>              MB = 4 (cm)

Vậy BM = 4cm

b) Vì I là trung điểm của đoạn thẳng BM

=> MI = 1/2. BM = 1/2 . 4 = 2(cm)

=> AM = MI (1)

Ta có:  điểm A thuộc tia MA

            điểm I thuộc tia MB

mà MA và MB là 2 tia đối nhau => điểm M nằm giữa 2 điểm A và I (2)

Từ (1) và (2) => M là trung điểm của AI

\(\frac{a^2+b^2}{b^2+c^2}=\frac{a^2+ac}{ac+c^2}=\frac{a\left(a+c\right)}{c\left(c+a\right)}=\frac{a}{c}\)

\(\RightarrowĐPCM\)

Easy! Một dòng là đủ!=))

Ta có: \(\frac{a^2+b^2}{b^2+c^2}=\frac{a^2+ac}{ac+c^2}=\frac{a\left(a+c\right)}{c\left(a+c\right)}=\frac{a}{c}^{\left(đpcm\right)}\) (do \(b^2=ac\))

41/24 - 2 x 1/2x + 2 x 5 = 0

41/24 - x + 10 = 0

x + 10 = 41/24

x = 41/24 - 10

x = - 199/24
