Answer» Answer: Prime factor of 2925 = 5 x 5 x 3 x 3 x 13 so to make it a perfect SQUARE we have to DIVIDE it by 13. so REQUIRED perfect square number is $\frac{2925}{13} = 225 \\ therefore \: \sqrt{225} = \sqrt{5 \times 5 \times 3 \times 3} = 5 \times 3 = 15$

Answer»

Answer:

Prime factor of 2925 = 5 x 5 x 3 x 3 x 13

so to make it a perfect SQUARE we have to DIVIDE it by 13.

so REQUIRED perfect square number is

$\frac{2925}{13} = 225 \\ therefore \: \sqrt{225} = \sqrt{5 \times 5 \times 3 \times 3} = 5 \times 3 = 15$
