Answer:
= 1/3 * sqrt(1/2)
Step-by-step explanation:
sqrt(1/18)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
sqrt(1/18)
sqrt(1)/sqrt(18)
1/sqrt(18)
We also know that sqrt(ab) = sqrt(a) sqrt(b)
1/sqrt(18) = 1/ sqrt(9)sqrt(2)
= 1/(3sqrt(2))
= 1/3 * 1/ sqrt(2)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
= 1/3 * sqrt(1/2)
