Give me a second while I type out the expression. Thank you

$\huge\frac{\sqrt{10}}{\sqrt{5}-2}$

anonymous · Answer

do you know the root of ten?

jamierox4ev3r · Answer

yes. The root of 10 is not rational, so I don't see how knowing that would help me solve this problem

jamierox4ev3r · Answer

$\huge\sqrt{10} = 3.16227766...$

jamierox4ev3r · Answer

I have a very limited recollection on rationalizing. So an explanation on that would be nice as well, thank you

anonymous · Answer

i learned that you can use a perfect number to minimalize something like this
heres an example the root of 18 equals 3root2

nincompoop · Answer

jamierox4ev3r · Answer

a conjugate...so like the opposite? do you mean multiplying by $\huge\sqrt{5}+2$ ??
