Question

root 99 X root 396 ​

Answer 1

Step-by-step explanation:

$\sqrt{99} \times \sqrt{396} \\ {99}^{ \frac{1}{2} } \times {396}^{ \frac{1}{2} } \\ ( {99 \times 396})^{ \frac{1}{2} } \\ ( {39204)}^{ \frac{1}{2} } \\ ({198})^{ ({2})^{ \frac{1}{2} } } \\ 198$

Answer 2

Answer:

198

Step-by-step explanation:

(99)^1/2 × (396)^1/2

=(3×3×11)^1/2 ×(11×6×6)^1/2(using exponent rule a^1/2 × b^1/2=(ab)^1/2)

=(3×3×11×11×6×6)^1/2

=3×11×6

=198
