√2/(√6+2) সমান-
Solution
Correct Answer: Option C
√2/(√6 + 2)
= √2(√6 - 2)/(√6 + 2)(√6 - 2)
= √2(√6 - 2)/{(√6)² - 2²}
= √2(√6 - 2)/(6 - 4)
= √2(√6 - 2)/2
= √2√2(√3 - √2)/2
= 2(√3 - √2)/2
= √3 - √2
= √2(√6 - 2)/(√6 + 2)(√6 - 2)
= √2(√6 - 2)/{(√6)² - 2²}
= √2(√6 - 2)/(6 - 4)
= √2(√6 - 2)/2
= √2√2(√3 - √2)/2
= 2(√3 - √2)/2
= √3 - √2
