Write the rationalizing factor of the following.

Given, 2∛5

Need to find the rationalizing factor

⇒ We know that if the product of two surds is rational then each is called a rationalizing factor of each other

⇒ 2∛5 ×

= 2( )

= 2 ( )

= 2 (5) = 10 is rational number

Hence, is rationalizing factor
