Question

If $a$ and $b$ are two different positive real numbers, then which of the following relations is true

$2 \sqrt{a b} > (a + b)$
$2 \sqrt{a b} < (a + b)$
$2 \sqrt{a b} = (a + b)$
None of these

The correct answer is: $2 square root of a b end root less than left parenthesis a plus b right parenthesis$

we are asked to find which of the following relation is true
We know that AM ≥ GM
(a+b)/2 ≥ √(ab)
(a+b) ≥ 2√ab

Therefore the correction option in choice 2
