-√18 over √12 simplify

To simplify √18 over √12, we divide the two square roots:

√18 / √12

First, factor both numbers under the square roots to simplify them further:
√(9 x 2) / √(4 x 3)

Now, simplify:
√9 x √2 / √4 x √3
3√2 / 2√3

Finally, we simplify by multiplying both numerator and denominator by the conjugate of the denominator to rationalize the denominator:
(3√2 / 2√3) x (2√3 / 2√3)
= 6√6 / 6
= √6
