Question
The largest real number among 
__________.
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- 2√3, 4√15 and 3√2
TO FIND-
Largest real number among the given numbers.
SOLUTION-
We know that-
3√2 = √(3*3) * √2 = √9 * √2 = √18 ...................................... (m = √m * √m)
2√3 = √(2*2) * √3 = √4 * √3 = √12 ...................................... (m = √m * √m)
4√15 = √(4*4) * √15 = √16 * √15 = √240 ...................................... (m = √m * √m)
Hence, we need to find the largest real number among √12, √18 and √240, which is √240 i.e. 4√15
