Please find the answer , it is a very importatnt question
Anna [14]

Step-by-step explanation:

The given expression is :

\dfrac{2-\sqrt5}{2+3\sqrt5}=\sqrt5 x+y ....(1)

Taking LHS of the above expression

\dfrac{2-\sqrt5}{2+3\sqrt5}

Rationalizing both denominator and numerator.

\dfrac{2-\sqrt5}{2+3\sqrt5}\times \dfrac{2-3\sqrt5}{2-3\sqrt5}=\dfrac{4-6\sqrt5-2\sqrt5+15}{2^2-(3\sqrt5)^2}\\\\=\dfrac{19-8\sqrt5}{4-45}\\\\=\dfrac{19-8\sqrt5}{-41}\\\\=\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})

Equation (1) becomes,

\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})=\sqrt 5\ x+y

Equating both sides,

x=\dfrac{8}{41} and y=\dfrac{-19}{41}

Hence, this is the required solution.
