Factor 256x^3 - 500y^3

Lady bird [3.3K]

(256 • (x3) - ( 2^2• 5^3 y^3)
______________________________________________________________
 2^8 x^3 - ( 2^2 • 5^3 y^3)

256x^3 - 500y^3 = 4 • (64x^3 - 125y^3)

64x^3 - 125y^3

a firm wants to select a group of 8 out of its 20 employees to attend a Business trip .in how many ways can this be done if ther

inna [77]

Answer:

Case 1 - 50388 ways when the couple is there in the group of 8 people selected out of 20 employees.

Case 2 - 75582 ways when the couple is not there in the group of 8 people selected out of 20 employees.

Step-by-step explanation:

Given

The couple within the group can not be separated and hence instead of taking total 20 employees , it must be taken as 19 employees.

Now if the couple is there in the selected group of 8 people, then total 7 needs to be selected out of 19 and hence the total number of ways of selecting 7 people out of 19 is

$^7C_{19}$ = 50388
