Question

simplify each of the following by rationalizing the denominator 6 minus 4 root 2 by 6 + 4 root 2​

Answer 1

Answer:

answer is 17 -12√2

Explanation:

(6 - 4√2)/(6 + 4√2)

(6 - 4√2)/(6 + 4√2) × (6 - 4√2)/(6 - 4√2)

(6 - 4√2)²/[(6)² - (4√2)²]

(36 + 32 - 48√2)/[36 - 32]

(68 - 48√2)/4

4(17 - 12√2)/4

= 17 - 12√2
