(1 point) Find the equation of the tangent plane to the surface z = e-X/In(3y) at the point (2, 4, 3.144). Z=The equation of the tangent plane to the sunface (2x/ 17) in (35) at the point ( 2 , 4 , 3 . 14 4 ) is 7 = 0 . 3 70 x + 0 . 31 6 7 + 1. 139 Note : we use this formula : The equation of the tangent plane to the sunface f ( x,yiz, at the point 20 , 401 20 ) 's FX ( X10 , YO, 20) ( x - 20 ) + Fy ( 20, yo, 20 ) ( y - to ) + F 2 ( XO , YO , 20 ) ( Z - 20 ) = 0
