a) ...Giâm cành................ là cắt 1 đoạn cành có đủ mắt chồi cắm xuống đất ẩm cho cành bén rễ mọc chồi tạo thành cây mới (0,5 điểm)

b) ...Chiết cành..................là làm cho cành ra rễ ngay trên cây rồi mới cắt ra trồng làm cây mới (0,5 điểm)

thân dài ra do phần ngọn

rễ cọc : cây đậu xanh , cây xoài , cây nhãn , cây phượng, cây bàng , cây bưởi , ...

rễ chùm : cây hành , cây tỏi , cây lúa , cây hẹ , cây rau cần , ...

\(\dfrac{1}{x}\)+ \(\dfrac{3}{x^2-3x}\) = \(\dfrac{x+3}{3-x}\)

x(x-3) \(\ne\) 0 \(\Rightarrow\) x \(\ne\) 0 và x-3 \(\ne\) 0

\(\Rightarrow\) x \(\ne\) 0 và x \(\ne\) 3

ĐKXĐ: x\(\ne\) 0 ; x \(\ne\) 3

Phương trình \(\Leftrightarrow\) \(\dfrac{1}{x}+\dfrac{3}{x\left(x-3\right)}=\dfrac{-x-3}{x-3}\)

\(\Leftrightarrow\) \(\dfrac{x-3}{x\left(x-3\right)}\) + \(\dfrac{3}{x\left(x-3\right)}\) = \(\dfrac{x\left(-x-3\right)}{x\left(x-3\right)}\)

\(\Leftrightarrow\) x - 3 +3 = -x^2 -3x

\(\Leftrightarrow\) x^2 +4x =0

\(\Leftrightarrow\) x(x+4) = 0

\(\Leftrightarrow\) \(\left[{}\begin{matrix}x=0\\x+4=0\end{matrix}\right.\) \(\Leftrightarrow\) \(\left[{}\begin{matrix}x=0\left(loại\right)\\x=-4\left(thoảman\right)\end{matrix}\right.\)

Vậy tập nghiệm của phương trình là S = \(\left\{-4\right\}\)

Ta biến đổi như sau:

a,b x 0,a x 0,b = 0,bbb

=> ab x a x b = bbb

=> ab x a x b = b x 100 + b x 10 + b

=> ab x a x b = b x 111 (Chia 2 vế cho b và phân tích số 111 thành tích 37 x 3 ta được)

=> ab x a = 37 x 3

Dễ dàng nhận thấy a = 3 và b = 7
