Question

Simplify root50-root98+root162

Answer 1

Hey friend,
Here is the answer you were looking for:
$\sqrt{50} - \sqrt{98} + \sqrt{162} \\ \\ = \sqrt{2 \times 5 \times 5} - \sqrt{2 \times 7 \times 7} + \sqrt{2 \times 9 \times 9} \\ \\ = 5 \sqrt{2} - 7 \sqrt{2} + 9 \sqrt{2} \\ \\ = 14 \sqrt{2} - 7 \sqrt{2} \\ \\ = 7 \sqrt{2}$

Hope this helps!!!
