Answer 8

Alternate method: Find out what prime number the given number is divisible by, then keep dividing by that number until you get a perfect square. In this case 1 + 0 + 2 + 9 = 12 which is divisible by 3, therefore, dividing by multiples of three yields:

\(\sqrt{49 \times 21}\)

Next split the square root:

\(\sqrt{49} \times \sqrt{21}\)

Now take the square root of 49:

\(7\sqrt{21}\)
