Answer 1

Answer:   $\bold{C)\ 15\sqrt2}$

Step-by-step explanation:

Simply each radical (groups of two factors on the side, make one factor on the outside).  Then add the like terms (same radical).

$\sqrt{8}+\sqrt{98}+\sqrt{72}\\\\=\sqrt{2\cdot 2\cdot 2}+\sqrt{2\cdot 7\cdot 7}+\sqrt{2\cdot 6\cdot 6}\\\\=2\sqrt{2}+7\sqrt{2}+6\sqrt{2}\\\\=(2+7+6)\sqrt2\\\\=15\sqrt2$
