Question

what is the rationalising factor of 1upon root 12 it is root 3 or 1 upon root 12
pls tell​

Answer 1

Step-by-step explanation:

$\frac{1}{ \sqrt{12 } } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{ \sqrt{3} }{ \sqrt{2 \times 2 \times 3 \times 3}} = \frac{ \sqrt{3} }{2 \times 3} = \frac{ \sqrt{3} }{6}$

here's your answer

the way to do this is to find the prime factors of the denominator. Now, in this case, prime factors of 12 are

• 2
• 2
• 3

now, to rationalise 12, we need 3, hence the rationalising factor is √3
