Question

By which smallest number should we multiply 1568 to make it a perfect square? ​

Answer 1

Answer:

2

Step-by-step explanation:

Prime Factorisation of 1568 = 2 x 2 x 2 x 2 x 2 x 7 x 7

Perfect square number pairs = (2 x 2) (2 x 2) x 2 x (7 x 7)

Here, 2 doesn't have pair.

So, 2 should be multiplied 1568 to make it a perfect square.

2 is the smallest number should we multiply 1568 to make it a perfect square.

Answer 2

Answer:

The smallest number which should be multipied to 1568 is 2.

Step-by-step explanation:

1568 =>

Prime factorisation of 1568 = 2 × 2 × 2 × 14 × 14

> 2 left unpaired.

> 2 does not form the pair of the product of two equal prime numbers.

Hence,

2 is the smallest number by which 1568 should be multiplied to make it a perfect sqaure.
