Answer 1

Answer:

2*2*2*2*9=144

√144

=12

Answer 2

Step-by-step explanation:

$\sqrt{2 \times 2 \times 2 \times 2 \times 9} \\ \\ = > \sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3} \\ = > \sqrt{4 \times 4 \times 9} \\ since, \\ \sqrt{4 = 2} \: and \: \sqrt{9} = 3 \\ hence, \\ \sqrt{4 \times 4 \times 9} \\ = > 2 \times 2 \times 3 \\ = > 4 \times 3 \\ = > 12$
