Let \(f(x)=x^2+9, g(x)=\frac{x}{x-9}\) and \(a =f \circ g(10), b =g \circ f(3)\). If \(e\) and \(l\) denote the eccentricity and the length of the latus rectum of the ellipse \(\frac{x^2}{a}+\frac{y^2}{b}=1\), then \(8 e ^2+l^2\) is equal to. 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
