Algebra Question

Answer 1

\[\frac{ \sqrt{18} }{ \sqrt{10} }\]

Answer 2

\[3\div \sqrt{5}\]

Answer 3

\[\frac{ 3\sqrt{2} }{ \sqrt{10} }\]

Answer 4

if your check in your calculator it should give you the same answer,
sqrt(18)/sqrt(10) = 1.341...
3*sqrt(2)/sqrt(10)= 1.341..
these are call surds.

Answer 5

or you can do what jk24 has done,
\[\frac{ 3\sqrt{2} }{ \sqrt{2}\times \sqrt{5} }\]

so you see \[\sqrt{2}\] cancel each other.

Answer 6

Yeah but you can't have a fraction in the denominator.
