कौन-सी संख्या \(\sqrt{27}+\sqrt{12}\) का सरल रूप है?
Which number is the simplified form of \(\sqrt{27}+\sqrt{12}\)?
Explanation opens after your attempt
Correct Answer
A. \(5\sqrt{3}\)
Concept
\(\sqrt{27}=3\sqrt{3}\) and \(\sqrt{12}=2\sqrt{3}\).
Why this answer is correct
The sum is \(3\sqrt{3}+2\sqrt{3}=5\sqrt{3}\), which is irrational.
Exam Tip
Do not combine separate square roots as \(\sqrt{39}\). चरण 1: \(\sqrt{27}=3\sqrt{3}\) और \(\sqrt{12}=2\sqrt{3}\)। चरण 2: योग \(3\sqrt{3}+2\sqrt{3}=5\sqrt{3}\), जो अपरिमेय है। चरण 3: अलग-अलग मूलों को सीधे जोड़कर \(\sqrt{39}\) न लिखें।
