\(\frac{30}{13}=\frac{26}{13}+\frac{4}{13}=2+\frac{1}{\frac{13}{4}}=2+\frac{1}{3+\frac{1}{4}}\)

a =2 ; b =3 ; c =4

Số abc = 234

cai nay minh tinh ko ra

\(y=\frac{1}{x^2+\sqrt{x}}\)

bài này tao cũng ko làm được,

30 / 13 = 26/13+4/13 = 2+ 1  /  13/4 = 2  + 1  /   3 + 1/4 

suy ra a = 2 b = 3  c = 4

abc = 234

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

vậy a = 2; b= 3 ; c= 4 , tịk mk nha

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 )

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

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

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