Question

m =

1
/3 − √8

and n =
1
/3 + √8

, calculate :

(i) mn​

Answer 1

Answer: 1

You look tired

It's simple as this

$mn=\frac{1}{(3-\sqrt{8} )(3+\sqrt{8} )} =1$

Answer 2

Answer:

n = 1/3 + √8

m = 1/3 - √8

so,

m x n =

(1/3 - √8) x (1/3 + √8)

(a + b) x ( a - b) =  a² - b²

(1/3)² - (√8)²

1/9 - 8

lcm

1 - 72/9

-71/9
