Answer 2

Answer:

m = (73 - 12 root 2) , n = (73 + 12 root 2) , mn = -71/9

Step-by-step explanation:

Given, m = 1 / 3 - 2 root 2 and n = 1/3 + 2 root 2

m = 1/3 - 2 root 2

m² = (1/3 - 2 root 2)²

=> m² = 1/9 + 8 - (4 root 2) / 3

LCM OF 9,3 is 9.

=> m² = (1 + 72 - 12 root 2) / 9

=> m² = (73 - 12 root 2) / 9.

n = 1/3 + 2 root 2

=> n² = (1/3 + 2 root 2)²

=> n² = 1/9 + 8 + (4 root 2) / 3

LCM OF 9,3 is 9.

=> n² = (1 + 72 + 12 root 2 ) / 9

=> n² = ( 73 + 12 root 2 ) / 9.

mn = (1/3 - 2 root 2) (1/3 + 2 root 2)

=> mn = (1/3)² - (2 root 2)²

=> mn = 1/9 - 8

=> mn = (1 - 72) / 9

=> mn = - 71 / 9
