Question

For each of the following numbers, 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.
(1) 252

​

Answer 1

Answer:

(i) 252 = 2 x 2 x 3 x 3 x 7

Here, 2 and 3 are in pairs but 7 needs a pair. Thus, 7 can become pair after multiplying 252 with 7.

So, 252 will become a perfect square when multiplied by 7.

Thus, Answer = 7

square no.=252x7=1764

square root of 1764=42
