Question
The smallest real number among
is ___________.
Hint:
1. Rational numbers refer to those numbers that can be represented as a simple fraction.
2. Irrational numbers refer to those numbers that cannot be represented as a simple fraction.
3. Real numbers is a union of both rational & irrational numbers.
The correct answer is: 
GIVEN-
Given numbers- 6√2, 2√6, 2√3 and 4√3
TO FIND-
Smallest real number among the given numbers.
SOLUTION-
We know that-
6√2 = √(6*6) * √2 = √36 * √2 = √72 ...................................... (m = √m * √m)
2√6 = √(2*2) * √6 = √4 * √6 = √24 ...................................... (m = √m * √m)
2√3 = √(2*2) * √3 = √4 * √3 = √12 ...................................... (m = √m * √m)
4√3 = √(4*4) * √3 = √16 * √3 = √48 ...................................... (m = √m * √m)
Hence, we need to find the smallest real number among √12, √24, √48 and √72, which is √12 i.e. 2√3
FINAL ANSWER-
Option 'a' i.e. '2√3' is the correct answer to the given question.
