Theo đề bài ta có :
7 ( a - b ) = 1 ( a+b) = 24( a. b )
7a - 7b = a - b = 24 ab
6a = 8b = 24ab => a = 24 : b (1)
6a = 8b => \(\frac{a}{8}\) = \(\frac{b}{6}\) (2)
Thay (1) vào (2) , ta có:
\(\frac{24}{\frac{b}{8}}\) = \(\frac{b}{6}\) => \(\frac{3}{b}\) = \(\frac{b}{6}\) => \(b^2\) = 3 . 6 = 18 => b = \(\sqrt{18}\)
=> a= 24 ; b = 24 : \(\sqrt{18}\) = \(\sqrt{2^5}\)
