Question

By what factor must you multiply a number in order to double its square root?

Answer 1

If the number is multiplied by 4, its square root is doubled.
In the same way, to multiply it's square root by 4, multiply it by 16.

Answer 2

4

Explanation:

Square root of a number can be found by using two methods.

One is prime factorization and other is long division method.

In prime factorization method, we have to make pairing of 2

For example square root of
`x^(2)` is x

`\sqrt{x^(2) }`= x

We have to find the double of square root than we have to multiply by 4 i.e, a pair of 2

square root of 4
`x^(2)` is 2x

Hence, the correct answer is we have to multiply by 4
