Answer:
(x - 9)(x^2 + 18x + 81).
Step-by-step explanation:
Use the difference of cubes factorization, which claims that a^3 - b^3 = (a - b)(a^2 + ab + b^2)
x^3 - 729 = (x - 9)(x^2 + 18x + 81)
As, order is important so we use permutation,
total no. of students= n=8
selected students= r=3
nPr= n!/(n-r)! = 8!/(8-3)! =336 different ways
So
C=10
3c+c/2c means
3(10)+10/2(10)
30+10/20
40/20=2
