Question

Find the value of (1)^-2. ​

Answer 1

Answer:

1/2 or 0.5

In mathematics, n! is the number of permutations of n things taken all at a time and is

n (n-1) (n-2)……. to n factors

or, n (n-1) (n-2)………..3.2.1.

n! is read “factorial n”. In the present problem, n = 2 and, therefore, 2! = 2.1 = 2. Hence,

1/2! = 1/2 = .5

There is no ambiguity in the question as to whether it is 1/2! or (1/2)! . The question is absolutely clear that it is 1 divided by factorial 2 and not factorial 1/2 .
