Question

The product of $\sqrt{a^{2}b}$ and $\sqrt{ab}$ is

• A. $ab\sqrt{a}$
• B. $a\sqrt{ab}$
• C. $\sqrt{ab}$
• D. $b\sqrt{ab}$

Answer 1

The correct option is A $ab\sqrt{a}$

$\sqrt{a^{2}b}\times \sqrt{ab}=\sqrt{a^2}\sqrt{b}\times \sqrt{a}\sqrt{b}$

$=ab\sqrt{a}$

$\therefore$ $\sqrt{a^{2}b}\times \sqrt{ab}=ab\sqrt{a}$.
