₁₀P₈ is a single number. You have written 4 numbers. Which is your intended answer? (None of them are correct.) Do you know the definition of "_nP_m"?

(A calculator is not necessary. I suspect the reason the problem said "simplify" is that this can be written as the product of two simple numbers.)

I think it is convention that nPr = n!/(n - r)!

I was asking yamuna. If he/she knows the definition of _nP_r, this should be a simple problem.
