Question

rationalize factor of 1/✓18​

Answer 1

Understanding the concept:

•We are given a term 1/√18 and we are said to rationalise it so firstly we will take the denominator same number at the right hand side same in numerator and denominator and then multiple the fractions and after multiplied then we will get the value.So let's find it!

First of all we will take same number at right hand side.

$\: \sf \implies \: \frac{1 }{ \sqrt{18} } \times \frac{ \sqrt{18} }{ \sqrt{18} }$

After taking common numbers now we will multiple the fractions

$\: \sf \implies \: \frac{ \sqrt{18} }{ { (\sqrt{18}) }^{2} }$

As we know when same square root numbers multiplied with same square root numbers then it will the number which is in square root so now find the value.

$\: \sf \implies \: \frac{ \sqrt{18} }{ \sqrt{18} \times \sqrt{18} }$

$\implies$$\large{\sf{\underline{\boxed{\green{{\dfrac{√18}{18}}}}}}}$
