Question

Ratonalise the denominator : 1/ root2 + root3 + root5

Answer 1

Answer:

$\boxed{\underline{\bf{\frac{1}{10}}}}$

Step by step explaination:

• To rationalize the denominator, we have to multiply both numerator and denominator with themselves by changing signs .

➙ $\boxed{\underline{\bf{\frac{1}{√2+√3+√5}}}}$

➙ Negative of the number = $\boxed{\underline{\bf{\frac{-1}{-√2+(-√3)+(-√5)}}}}$

➙ Solution :

$\boxed{\underline{\bf{\frac{1}{√2+√3+√5}}}}$ × $\boxed{\underline{\bf{\frac{-1}{-√2+(-√3)+(-√5)}}}}$

= $\boxed{\underline{\bf{\frac{-1}{-2+(-3)+(-5)}}}}$

= $\boxed{\underline{\bf{\frac{-1}{-2-3-5}}}}$

= $\boxed{\underline{\bf{\frac{1}{10}}}}$
