You'll get used to these as you get more questions and do them. Let me start you off. Whenever you have a question like this where multiplication is solely involved (as you're multiplying 49 x b) you can split them apart into two individual square roots multiplied together. So, if you're dealing with:
sqrt%28125%29
you can rewrite it as:
sqrt%285%29%2Asqrt%2825%29
because 5x25 is equivalent to 125. But take note of the fact that you can rewrite the square root of 25 as 5, so you'll get the following as your final answer:
5%2Asqrt%285%29


----------------------------------------------------------------------


Now let's move on to your problem.
sqrt%2849%2Ab%29
sqrt%2849%29%2Asqrt%28b%29 (we can find the square root of 49)
7%2Asqrt%28b%29 (your final answer)


Pretty simple eh?
