Answer» Given : X and y are 2 distinct positive integers To find : mean of x and y is always greater than Solution: x and y are 2 distinct positive integer s then mean of x and y is always greater than root ( xy ) x & y are distinct positive integer => Mean = (x + y )/2 as we KNOW that (√x - √ y )² > 0 if x & y are distnicts => x + y - 2√xy > 0 => x + y > 2√xy => (x + y)/2 > √xy mean of x and y is always greater than √xy Learn more: Three unequal positive NUMBERS a, b, c are in gp then prove that a + ... |
