\(\frac{30}{43}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)thế này à           

a = 1   ;     b = 2     ; c = 3    : d = 4

\(\frac{30}{43}=\frac{1}{\frac{43}{30}}=\frac{1}{1+\frac{13}{30}}=\frac{1}{1+\frac{1}{\frac{30}{13}}}=\frac{1}{1+\frac{1}{2+\frac{4}{13}}}=\frac{1}{1+\frac{1}{2+\frac{1}{\frac{13}{4}}}}=\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)

Vay a=1; b=2; c=3; d=4

Ai là hs giỏi thì giúp mik vs mai nộp rồi

Ta có : \(\frac{30}{43}=\frac{1}{\frac{43}{30}}=\frac{1}{1+\frac{13}{30}}=\frac{1}{1+\frac{1}{2+\frac{4}{13}}}=\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)

Vậy a = 1,b = 2,c = 3,d = 4

\(\frac{30}{43}=\frac{1}{\frac{43}{30}}=\frac{1}{1+\frac{13}{30}}=\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)

Vậy a = 1;b=2;c=3;d=4 ( thỏa mãn )

30/43=1/43/30=1/1+13/30=1/1+1/30/13=1/1+1/30/13=1/1+1/2+4/13=1/1+1/2+1/13/4=1/1+1/2+1/3+1/4

vậy a=1, b=2, c=3, d=4

\(\frac{30}{43}=\frac{1}{\frac{43}{30}}=\frac{1}{1+\frac{13}{30}}=\frac{1}{1+\frac{1}{\frac{30}{13}}}=\frac{1}{1+\frac{1}{2+\frac{4}{13}}}=\frac{1}{1+\frac{1}{2+\frac{1}{\frac{13}{4}}}}=\)

$\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}$

Vậy a = 1 ; b = 2 ; c = 3 ; d =4

\(\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)

Viết nhầm xíu

\(\frac{30}{43}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)\(\Rightarrow\frac{1}{\frac{43}{30}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)

\(\Rightarrow\frac{1}{1+\frac{13}{30}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)\(\Rightarrow\frac{1}{1+\frac{1}{\frac{30}{13}}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)\(\Rightarrow\frac{1}{1+\frac{1}{2+\frac{4}{13}}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)\(\Rightarrow\frac{1}{1+\frac{1}{2+\frac{1}{\frac{13}{4}}}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)\(\Rightarrow\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)

\(\Rightarrow a=1,b=2,c=3,d=4\)

\(\frac{30}{43}\)=\(\frac{1}{\frac{43}{30}}\)= \(\frac{1}{1+\frac{13}{30}}\)=\(\frac{1}{1+\frac{1}{2+\frac{4}{13}}}\)=\(\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)

=> a=1,b=2,c=3,d=4.

Suy nghĩ đi, chỗ nào ko hiểu hỏi mình, lát mình quay lại giờ mình bận.
