JEE MainMathematicsDefinite IntegrationNumerical+4 / −1
Let F:[3,5]→RF:[3,5] \to RF:[3,5]→R be a twice differentiable function on (3, 5) such that F(x)=e−x∫3x(3t2+2t+4F′(t))dtF(x) = {e^{ - x}}\int\limits_3^x {(3{t^2} + 2t + 4F'(t))dt}F(x)=e−x3∫x​(3t2+2t+4F′(t))dt. If F′(4)=αeβ−224(eβ−4)2F'(4) = {{\alpha {e^\beta } - 224} \over {{{({e^\beta } - 4)}^2}}}F′(4)=(eβ−4)2αeβ−224​, then α\alphaα+β\betaβ is equal to ‾\underline{\hspace{2cm}}​.
