Final answer:

To simplify the square root of 7/18, divide the numerator and denominator into their prime factors and cancel out common factors.

Step-by-step explanation:

To simplify the square root of 7/18, we can break down the numerator and denominator into their prime factors:

7 = 7

18 = 2 * 3 * 3

Now, we can cancel out any common factors between the numerator and denominator, which in this case is a factor of 3:

7/18 = 7/(2 * 3 * 3) = 7/(2 * 3 * 3) = 7/(2 * 3) = 7/6

Therefore, the simplified square root of 7/18 is (√7)/√6, since the square root of 6 is still in the denominator.

sqrt (7/18)

sqrt(7)/sqrt(18)

no sqrt in the denominator

sqrt(7)/sqrt(18) * sqrt(18)/sqrt(18)

sqrt(7*18)

------------

18

sqrt(126)/18

sqrt(9*14)/18

sqrt(9) *sqrt(14)/18

3*sqrt(14)/18

sqrt(14)/6
