Answer 1

Answer:

1608

Step-by-step explanation:

$\sqrt{12864}$

=

$\sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 67}$

Since 3 and 67 are not in pair we will multiply the given no. by 3 and 67 to make it a perfect square.

=

$\sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 67 \times 67}$

=2*2*2*3*67

=1608
