Question

Evaluate the expression.
9P0

Answer 1

\[_9P_0 = \frac{ 9! }{ 0! \times 9! }\] do you mean this?

Answer 2

Yes, thank you. :)

Answer 3

so my answer was 9 is that correct?

Answer 4

Nope, because 0! = 1 and 9!/9! cancel each other out hence your answer will be left as 1/(1x1) = 1

Answer 5

1, thank you...it makes total sense now.
