Question

simplify √72+√800-√18 ​

Answer 1

$\sqrt{12} + \sqrt{800} - \sqrt{18}$

$= \sqrt{6 \times 6 \times 2} + \sqrt{20 \times 20 \times 2} + \sqrt{2 \times 3 \times 3}$

$= 6\sqrt{2} + 20 \sqrt{2} - 3 \sqrt{2}$

$= 26\sqrt{2} - 3 \sqrt{2}$

$= 33 \sqrt{2}$

$= 26 \sqrt{2} + 20 \sqrt{2} + 3 \sqrt{2}$
