Question

if x+y = 11 and xy = 17 find the value of x³+y³
pls give right answer​

Answer 1

Answer:

x³+ y³​ = 1870

Step-by-step explanation:

Using Identity (x+y)³ = x³+ y³​ + 3xy(x + y)

⇒ x³+ y³​ = (x+y)³ - 3xy(x + y)

Substituting the given values, x+y = 11 and xy = 17

x³+ y³​ =  11³ - 3x17x11

= 11 x (121 - 51)

= 11 x 70

= 1870
