Answer:
Step-by-step explanation:
Solution :
3√2 is irrational number.
By multiplying 3√2 by √2, we get rational number.
= 3√2 ⋅ √2
= 3√(2 ⋅ 2)
Since we have two same numbers multiplying inside the radical, we can factor out one term.
= 3 ⋅ 2
= 6 is the rational number
Hence the rationalizing factor of 3√2 is √2.
