The value of the permutation expression 2p2 + nP1 is 2 + n
<h3>How to evaluate the
permutation expression?</h3>
The permutation expression is given as:
2p2 + nP1
The formula of permutation is
nPr = n!/(n - r)!
Using the above formula of permutation, we have:
2P2 = 2!/0!
2P2 = 2!/1
2P2 = 2!
2P2 = 2
nP1 = n!/(n - 1)!
nP1 = n * (n - 1)!/(n - 1)!
nP1 = n
Substitute 2P2 = 2 and nP1 = n in 2p2 + nP1
2p2 + nP1 = 2 + n
Hence, the value of the permutation expression 2p2 + nP1 is 2 + n
