>> The magnitude of V, again we're using V as 11, 4. So it's the square root of 11 squared plus 4 squared and all of that is squared. Well the squaring takes out the radical here so it's simply 11 squared plus 4 squared in the denominator. But making the calculation here we find this to be about 3.27. Now, that's 3.27 as a scalar multiple of the 11, 4 okay? And then we multiply 3.27 times 11, 4, we find this to be 36, 13.
