Question

4. Find the least number by which following numbers should be divided to get perfect
squares:
(i) 1200 (ii) 19845.​

Answer 1

Answer:

1)1200 is an even number, thus divisible by 2 and any positive integer multiple of 1200 will also be divisible by 2, making for a non-perfect square e.g. 1200* 3 = 3600 and sqrt(3600) = 60, but 60 is not prime since its constituent primes are 2*2*3*5, making 3600 a non-perfect square.

2)384 must be divided by 3×2=6 to make it a perfect square. 384/6=64 which is a perfect square...
