Not going to do all for you!
1. {{{highlight_green(matrix(3,3, " "[n]P[2], "=", 380, " "[20]P[2], "=", 380, n, "=", 20))}}}
2. {{{highlight_green(matrix(1,5, " "[10]P[5], "=", 10(9)(8)(7)(6), "=", "30,240"))}}}
3. {{{highlight_green(matrix(4,3, " "[8]P[r], "=", "20,160", 8(7)(6)(5)(4)(3), "=", "20,160", " "[8]P[6], "=", "20,160", r, "=", 6))}}}
