QuestionPerform the indicated operations where $b>0$. $$\sqrt{98 b}-\sqrt{200 b}+\sqrt{72 b}$$

Studdy Solution
Combine all the simplified terms:
$$7\sqrt{2b} - 10\sqrt{2b} + 6\sqrt{2b}$$
Combine the coefficients of $\sqrt{2b}$:
$$(7 - 10 + 6)\sqrt{2b} = 3\sqrt{2b}$$
The simplified expression is:
$$\boxed{3\sqrt{2b}}$$
