The value of 0.6912+0.52920.6912−0.5292{\sqrt{0.6912}+ \sqrt{0.5292}}\over{\sqrt{0.6912}- \sqrt{0.5292}} is _________.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 15

0.6912+0.52920.6912−0.5292{\sqrt{0.6912}+ \sqrt{0.5292}}\over{\sqrt{0.6912}- \sqrt{0.5292}}

⇒ [(√0.12 × √5.76) + (√0.12 × √4.41)]/[(√0.12 × √5.76) – (√0.12 × √4.41)]

⇒ [2.4 + 2.1]/[2.4 – 2.1]

⇒ 4.5/0.3

⇒ 15
