Answer:
Step-by-step explanation:
11C4 = 11! / (7!*4!) = 11 * 10 * 9 * 8 * 7!/ 7! * 4!
11C4 = 11*10 * 9 * 8 / 24
11C4 = 11*10 * 3
11C4 = 330

You can't do the second one. Permutations and Combinations always give an answer greater than 1 and integers.
Answer:

Step-by-step explanation:
1) so you want to simplify this monomial first
(divide coefficients by 7)
(3x^6y^5)/2x^2y^9
2) next, you want to eliminate the extra "x" and :y: values
(bring x value with smaller power to the higher power x value)
so
(3x^6*x^-2y^5)/2y^9
(3x^4y^5)/2y^9
(do same thing for "y")
(2x^4)/2y^4
