Write the rationalizing factor of the following.

Given, 3√2

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

⇒ 3√2 × √2 = (3)(√2)² = 6 is rational number

Hence, rationalizing factor of 3√2 is √2
