Answer 1

√11 + √44 - 2√99 + √176
√11 + √(4 . 11) - 2√(9 . 11) + √(16 . 11
√11 + √(2² . 11) - 2√(3² . 11) + √(4² . 11)
√11 + 2√11 - 2 . 3√11 + 4√11
√11 + 2√11 - 6√11 + 4√11
1√11
√11

Answer 2

$\sqrt{11} + \sqrt{4.11} -2 \sqrt{9.11} + \sqrt{16.11} \\ \sqrt{11} + 2 \sqrt{11} -2.3 \sqrt{11} +4 \sqrt{11} \\ 7 \sqrt{11} -6 \sqrt{11} \\ \sqrt{11}$
