Question

factorise 4root 2.please any one know the answer to this question​

Answer 1

Given Real number

$= \dfrac{4}{\sqrt{2} }$

For Solving, the denominator must be rationalized.

Here, to rationalize, the numerator and denominator must be multiplied by the given rational number.

$\implies \dfrac{4}{\sqrt{2} } \times \dfrac{\sqrt{2} }{\sqrt{2} }$

Multiplying, we get,

$\implies \dfrac{4\sqrt{2} }{2}$

Taking 2 common, we get,

$\implies 2(\dfrac{2\sqrt{2} }{2})$

$\implies 2\sqrt{2}$

$\boxed{\boxed{\bold{Therefore, \ 2\sqrt{2} \ is \ the \ answer}}}}}}}$
