Question

8. For each of the following numbers, find the smallest number by which we divide it so
as to get a perfect square. Also find the square root of the square numbers so
obtained.
a. 37845
b. 2800
C. 45056​

Answer 1

2800=2×2×2×2×5×5

Since the prime factor 7 does not in pairs.

Therefore,2800 is not a perfect square.

The smallest number by which 2800 must be divided to obtain a perfect square=7

Therefore cubic no.=2800÷7 = 400

square root =(2×2)×(2×2)×(5×5)

=2×2×5

=20(ans)

45056=2×2×2×2×2×2×2×2×2×2×2×2×11

Since the prime factor 11 does not occur in pairs.

therefore, 45056 is not a perfect square.

The smallest number by which 45056 must be divided to obtain a perfect square =11

therefore cubic no.=45056÷11 = 44096

square root=(2×2)×(2×2)×(2×2)×(2×2)×(2×2)×(2×2)

=2×2×2×2×2×2

=64 (ans)
