Math Review Day 2!

6a. Rationalize the expression and simplify

Answer 1

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

Answer 2

\(\huge\frac{\sqrt{10}}{\sqrt{5}-2}\)

Answer 3

do you know the root of ten?

Answer 4

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

Answer 5

\(\huge\sqrt{10} = 3.16227766...\)

Answer 6

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

Answer 7

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

Answer 8

do you want to see if you can do anything by multiplying it by a conjugate

Answer 9

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

Answer 10

o-o
