Hence 31 is the least number to be subtracted from 4000 to get a perfect square.

Prime factorization: 1323 = 3 × 3 × 3 × 7 × 7, which can be written 1323 = 3³ × 7² The exponents in the prime factorization are 3 and 2.

So now we know the digital root of 8,464 is 4. Is 4 in the list of digital roots that are always a square root (1, 4, 7 or 9)? Answer: YES, 4 is in the list of digital roots that are always perfect squares. We can conclude that 8,464 could be a perfect square!

So, the square root of 5184 can be written as √5184=2×2×2×3×3=72 . Hence, the square root of 5184 is 72. Note: While calculating square roots and cube roots, prime factorization is the easiest method.

A: No, the number 4,000 is not a perfect square.

So, 9 is subtracted from 1234.

1856-1684 = 172. Thus, to yield an integer that will leave a remainder of 4 when divided by 7, 12 and 16, the smallest value that must be subtracted from 1856 is 172.

Answer & Explanation Explanation: The numbers less than 696 and are squares of certain numbers are 676, 625. The least number that should be subtracted from 696 to make it perfect square = 696 – 676 = 20.

Step-by-step explanation: By performing long division, the last square before 2400 is (48)^2.

Therefore 2800 must be divided by 7 to make it a perfect square.

Hence the number to be added is 372−1300=1369−1300=69.

Answer. we must add 21 to 1500 to make it a perfect sq.

Hence, 200 must be multiplied by 2 to make it a perfect square. Was this answer helpful?

Answer. Therefore, you must add 18 to 5607 to get the sum to be a perfect square.

Answer. If you meant, “make the sum a perfect square” then you can answer the question. Therefore the smallest perfect square greater than 14841 is 122^2 or 14884. To get there from 14841 you would have to add 43.
