HOW DO I SOLVE THIS

This is just the combination "formula" for "44 choose 4"   =  C(44,4)

You can evaluate it with any scientific calculator  or ours   by pressing the "ncr" button

However....here is another [equivalent] form

[44 * 43 * 42 * 41] / 4!   = [ 44 * 43 * 42 * 41] / 24

$\frac{44!}{(44-4)!}\times4!$

$\frac{44!}{40!}\times4!$

$\frac{1\times2\times3\times4\times5\times6\times7\times8\times9\times10\times11\times12\times13\times14\times15\times16\times17\times18\times19\times20\times21\times22\times23\times24\times25\times26\times27\times28\times29\times31\times31\times32\times33\times34\times35\times36\times37\times38\times39\times40\times41\times42\times43\times44}{1\times2\times3\times4\times5\times6\times7\times8\times9\times10\times11\times12\times13\times14\times15\times16\times17\times18\times19\times20\times21\times22\times23\times24\times25\times26\times27\times28\times29\times30\times31\times32\times33\times34\times35\times36\times3\times38\times39\times40}\times1\times2\times3\times4$
