there is 8 letters in the word TREASURE
so,Start with the given expression
nPr=n%21%2F%28n-r%29%21......plug in n=8 and r=8
8P8=8%21%2F%288-8%29%21
8P8=8%21%2F%288-8%29%21....when you subtract 8-8 you get 0
8P8=8%21%2F0%21....calculate 8%21=8%2A7%2A6%2A5%2A4%2A3%2A2%2A1=40320 and 0%21=1
8P8=40320%2F1
8P8=40320
