√99 * √396
​

Answer 1

Answer:

198

Step-by-step explanation:

$\sqrt{99}$ = $\sqrt{11*9}$ = $3\sqrt{11}$ = 3 * $\sqrt{11}$

$\sqrt{396\\}$ = $\sqrt{99*4}$ = 2$\sqrt{11*9}$ = 2 * 3$\sqrt{11}$ = 2 * 3 * $\sqrt{11}$

$\sqrt{99}$ * $\sqrt{396\\}$ = 3 * $\sqrt{11}$ * 2 * 3 * $\sqrt{11}$

= 3 * 2 * 3 * $\sqrt{11}$ * $\sqrt{11}$

= 18 * 11

= 198
