Question

6 minus 4 root 3 upon 6 + 4 root 3

Answer 1

Hii friend,

6-4✓3/6+4✓3

=> 6-4✓3/6+4✓3 × 6-4✓3/6-4✓3

=> (6-4✓3)(6-4✓3)/(6+4✓3)(6-4✓3)

=> (6-4✓3)²/(6)² - (4✓3)²

=> (6)² +(4✓3)² - 2 × 6 × 4✓3/36- 48

=> 36 + 48 - 12 × 4✓3/-12

=> 84 - 48✓3/-12

=> 4(21-12✓3)/-12

=> 21-12✓3/-3

=> 21-12/-✓3

=> 21-12/-✓3 × ✓3/✓3

=> 21✓3-12✓3/-3

=> 9✓3/-3 = 3✓3/-1....

HOPE IT WILL HELP YOU.... :-)

Answer 2

Heya ✋

Let see your answer !!!

(6 - 4√3)/(6 + 4√3)

By rationalization

(6 - 4√3) × (6 - 4√3)/(6 + 4√3) × (6 - 4√3)

= (6 - 4√3)^2/(6)^2 - (4√3)^2

= (6)^2 - 2 × 6 × 4√3 + (4√3)^2/36 - 48)

= 36 - 48√3 + 48/-12

= 84 - 48√3/-12

= 84/-12 - 48√3/-12

= - 7 + 4√3
