see it's very easy to analyze:first find it's factors: 1050 = 2*3*5*5*7Now, as we can change the values between different xs.Soo, we get ans: 5!but we have two 5s. That's why, ans is 5!/2! = 60.

first find it's factors: 1050 = 2*3*5*5*7
Now, as we can change the values between different xs.
Soo, we get ans: 5!
but we have two 5s. That's why, ans is 5!/2! = 60.
