Question

0dx=_________

  1. k
  2. 0
  3. 1
  4. 1

Answer: k

Solution :-

We know thatd(k)dx=0(1)(where, k is some constant)

And we know that integration is an inverse process of Differentiation.
Now Integrate eq(1), we get d(k)dxdx=0dx

Hence, k=0dx(d(f(x))dxdx=f(x))

0dx=k

So, correct answer is option-1, k
