If `y=x^m e^(nx)` then `(d^2y)/(dx^2)` is

If y=e^(nx) then (d^(2)y)/(dx^(2)) is

y=x+e^(x), then (d^(2)y)/(dx^(2))=

If y = x+e^(x) , then (d^(2)y)/(dx^(2)) is equal to

If y = e^(x) sin x then (d^(2)y)/(dx^(2)) =

If y=x^(n)log nx.,then (d^(2)y)/(dx^(2))=

If y=a e^(m x)+b e^(-m x), then (d^(2y))/(dx^2) is equals to

If y=a e^(m x)+b e^(-m x), then (d^2y)/(dx^2) is equals to

If y=e^(x) , then (d^(2)y)/(dx^(2)) = e^(x) .

If y=a e^(m x)+b e^(-m x), then (d^(2y))/(dx^2)-m^2y is equal to m^2(a e^(m x)-b e^(-m x)) 1 (c) 0 (d) none of these
