For rationalising the denominator of the expression 1/√12
we multiply and divide by
(a)1/√12
(b)12
(c)√2
(d)√3
the answer is √3 but pls can you help me with process

Answer:
Root 3
Step-by-step explanation:
since 1/ root 12 can be expressed in the form 1/ 2 root 3
(12=4*3 and the sq root of root 4 is 2)
this leaves only 2 root 3 in the denominator to remove by multiplying and dividing it thus rationalising the denominator.
For rationalizing the denominator of the expression 1/√12 we multiply and divide by (d) √3
Let us factorize 12
12 = 4 x 3
12 = 2x 2 x 3
Write the factorized form of 12 in the expression
1 / √2x2x3
It can be written as
1 / 2√3
For rationalising a number, we have to remove the square root from the denominator
We divide and multiply 1 / 2√3 by √3
Rationalised form = (1 x √3 / 2√3 x √3 )
= √3 / 2x 3
= √3 /6
Therefore, for rationalizing 1/√12, we divide and multiply it by √3
The rationalized form of the number is √3 /6.
