In this game of mine, there are three words - " Ram , Shyam and Ghanshyam ", Let the number of ways can you arrange the letters of word "Ram" distinctly be denoted by 'a' .Similarly, let the number of ways can you arrange the word "Shyam" distinctly be denoted by ' b'.
So,,,,,,What is the square root of (a x b x 5) ?

You can arrange the 3 letters in Ram 3! ways or 3 × 2 × 1 or 6 ways. You can arrange the 5 letters in Shyam 5! ways, or 5 × 4 × 3 × 2 × 1 or 1 2 0 ways. 6 × 120 × 5 = 3 6 0 0 . 3 6 0 0 = 6 0 .
