Question

9th maths rationalize using the denominator
explaination in brief please anyone
​

Answer 1

We can rationalize any number

For example:

$\frac{5}{2 - \sqrt{3} } = \frac{5}{2 - \sqrt{3} } . \frac{2 + \sqrt{3} }{2 + \sqrt{3} }$

$= \frac{10 + 5 \sqrt{3} }{4 - 3}$

$= \frac{10 + 5 \sqrt{3} }{1}$

$= 10 + \sqrt[5]{3}$

Extra Explanation:

Rationalizing the denominator" is when we move a root (like a square root or cube root) from the bottom of a fraction to the top.

(The top number is the numerator and shows how many parts we have.)
