2800 - By which smallest number this number should be divided, so that the result becomes a perfect square? Find the square root of the result obtained.

Answer»

Hey MATE !!

the prime Factorization of 2800 is,

2800 = 2 × 2× 2 × 2 × 5 × 5 × 7

Here, all numbers are paired rather than 7. The number 7 is UNPAIRED. Hence, we should DIVIDE 2800 with 7.

2800/7 = 400

The REQUIRED number is 400.

The prime Factorization of 400 is,

400 = 2 × 2 × 2 × 2 × 5 × 5

Square root of 400 is 20
