Question 5 (iv)
For the following number, find the smallest whole number by which it should be multiplied so as to get a perfect square number. Also, find the square root of the square number so obtained:
2028
2028=2×2×3×13×13
Here, prime factor 3 has no pair. Therefore 2028 must be multiplied by 3 to make it a perfect square.
∴2028×3 = 6084
And √6084=2×2×3×3×13×13=78
