Question

Rationalize the denominator of radical 18 over radical 3?

Answer 1

.. √18 / √3
= [ √18 * √3 ] / [ √3 * √3 ]
= [ √(18 * 3) ] / 3
= [ √(6 * 3 * 3) ] / 3
= [ 3 √6 ] / 3
= √6

Answer 2

can you rationalize 3 over radical 2?

Answer 3

radical 3

two's cancel ( as long as the last two is not under the radical)

Answer 4

\[\Large \frac32 \sqrt2\] this is correct.

Answer 5

\[\frac{\sqrt{18}}{\sqrt{3}}=\sqrt{\frac{18}{3}}=\sqrt{6}\]no need for rationalizng denominator

Answer 6

\[\frac{3}{\sqrt{2}}=\frac{3}{\sqrt{2}}\times \frac{\sqrt{2}}{\sqrt{2}}=\frac{3\sqrt{2}}{2}\]this one does require rationalizing denominator

Answer 7

3 \cdot2 = \[3 \cdot 2\] on latex ;) @satellite73
