.................................​

Answer 1

Answer:

By using identity a-b²=a²+ b²-2ab is this A =

$a = \sqrt{11}$

$b = \sqrt{5}$

${ \sqrt{11} }^{2} + \sqrt{ {5}^{2} } - 2 \sqrt{11} \sqrt{5} \\ \\ square \: and \: root \: square \: will \: cancel \: \\ \\11 + 5 - \sqrt{22} \sqrt{10} \\ \\ 15 - \sqrt{220}$

so this will be the answer thank u
