Question

multiply 9√3 × 1/√27​

Answer 1

Answer:-

$\sf 9 \sqrt{3} \times \frac{1}{ \sqrt{27} }$

$\sf = 9 \sqrt{3} \times \frac{1}{ \sqrt{3 \times 9} }$

$\sf = 9 \cancel{\sqrt{3}} \times \frac{1}{ \cancel{ \sqrt{3}} \times \sqrt{9} }$

$\sf = \pm \frac{9}{3}$

$\sf = \pm 3$

This is the required answer.
