Question

find the simplest rationalising factor of 1/√50

Answer 1

Multiply by √2.
$\frac{1}{ \sqrt{50} } * \sqrt{2}= \sqrt{ \frac{2}{50} } = \sqrt{ \frac{1}{25} } = \frac{1}{5}$

Answer 2

Answer:

= 1 / 5

Step-by-step explanation:

Given : 1 /√ 5 0 .

To find : find the simplest rationalising factor of 1 /√ 5 0 .

Solution :

Hence, the simplest rationalising factor is 12 .

Firstly ,

let 1 /√ 5 0 . Multiply by √ 2 .

1 /√ 5 0 * √ 2

= √ 2 / 50

= √ 1 / 2 5

= 1 / 5

Thus ,

1 / 5 is the simplest rationalising factor .

Rationalising Factor: A number that must be multiplied in order to convert an irrational number to a rational number. For example, to convert the irrational number 3 to a rational number, multiply 3 by 3.
