✔ 最佳答案
=√2√3 - √2√7 = √6 - √14

â6 - â14

= sqrt 6 - sqrt 14

â6 - â14
2010-02-12 11:24 pm
â2(â3 - â7)
= â(2 * 3) - â(2 * 7)
= â6 - â14
= â(2 * 3) - â(2 * 7)
= â6 - â14
2010-02-12 11:10 pm
â2(â3 - â7)
= â6 - â14
= â6 - â14

When multiplying radicals, recall that you are allowed to multiply the numbers in side the radical symbol:
â2(â3 - â7),
â6-â14<-- That's your final number, as no perfect squares go into either 6 or 14.
Have a nice day :)
â2(â3 - â7),
â6-â14<-- That's your final number, as no perfect squares go into either 6 or 14.
Have a nice day :)

= (sqrt 2)(sqrt 3) + (sqrt 2)(sqrt -7)
= sqrt 6 - sqrt 14
= sqrt 6 - sqrt 14
