  1. 2 + 1/(2+1/(2+1/(2+1/2)))
    = 2 + 1/(2+1/(2+1/(5/2)))
    = 2 + 1/(2+1/(2+2/5))
    = 2 + 1/(2+1/(12/5))
    = 2 + 1/(2+5/12)
    = 2 + 1/(29/12)
    = 2 + 12/29
    = 70/29
    (Chúc bạn học tốt)
     

  2. Giải đáp:
    70/29
    Lời giải và giải thích chi tiết:
    $2+\dfrac{1}{2+\dfrac{1}{2+\dfrac{1}{2+\dfrac{1}{2}}}}\\=2+\dfrac{1}{2+\dfrac{1}{2+\dfrac{1}{\dfrac{5}{2}}}}\\=2+\dfrac{1}{2+\dfrac{1}{2+\dfrac{2}{5}}}\\=2+\dfrac{1}{2+\dfrac{1}{\dfrac{12}{5}}}\\=2+\dfrac{1}{2+\dfrac{5}{12}}\\=2+\dfrac{1}{\dfrac{29}{12}}\\=2+\dfrac{12}{29}\\=\dfrac{70}{29}$.
