An ellipse and a hyperbola have the same foci, $a$ and $b$, and intersect at four points. the ellipse has major axis 50, and minor axis 40. the hyperbola has conjugate axis of length 20. let $p$ be a point on both the hyperbola and ellipse. what is $pa \cdot pb$?

the answer for this question is 38

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
