|
Answer» माना ` " "y=x ^(10)` ` therefore " "(dy)/(dx) =(d)/(dx) (x^(10)) =10x^(9)` ` (d)/(dx) ((dy)/(dx))=(d^(2)y)/(dx^(2))=10 (d)/(dx)x^(9) =90x^(8)` ` (d)/(dx) ((d^(2)y)/(dx^(2)))= (d^(3)y)/(dx^(3))=90(d)/(dx) x^(8) =720x^(7)` तथा ` " "(d)/(dx) ((d^(3)y)/(dx^(3)))= (d^(4)y)/(dx^(4))=720(d)/(dx) x^(7) =5040x ^(6)` ` therefore " "(d^(4)y)/(dx^(4))=5040x ^(6)` |
