how many ways can 6 specific unique symbols be arranged?
Answer
Explanation:
Step1: Recall permutation formula
The number of permutations of (n) distinct objects is (n!). Here (n = 6).
Step2: Calculate factorial
(n!=n\times(n - 1)\times\cdots\times1), so (6!=6\times5\times4\times3\times2\times1). (6\times5 = 30), (30\times4=120), (120\times3 = 360), (360\times2=720), (720\times1 = 720).
Answer:
720
