Question

Find the smallest number by which 3920 should be multiplied so that the resulting number is a perfect square.

Answer 1

Answer:

The answer is 5

Step-by-step explanation:

To find the smallest number by which 3920 should be multiplied so that the resulting number is a perfect square, we have to use the method of prime factorization

Step 1 = By using prime factorization method find the factors of the number      3920

The factors are(after using the prime factorization method)-

2 X 2 X 2 X 2 X 5 X 7 X 7

As 5 is in not in the group(as it[3920] doesn't have another 5)

Step 2 = Then we will multiply the left out number(the number which isn't in the group) with 3920 to make it a perfect square.

This left out number[5] becomes the smallest number by which the number 3920 should be multiplied so that the resulting number is a perfect square
