dividing radicals helpppppp square root of 5 divided by 5 + square root of 2 2 - square root of 3divided by
\[\sqrt{5}\div5+\sqrt{2}\]
\[2-\sqrt{3}\div-2-\sqrt{5}\]
that would give you 1.861427128....
but how did u get that
the first one..gave you that
I have a texas ti-84 plues
i mean step by step
yea so do i
put it in you cal.
to put in the first problem
i know but i need to show the work
Oh
so in you cal. do square root of 5
i need to show the work on papaer
I dont know how to show it on paper...
ur teacher must be trippin
thnkss anyway
i guess
\[\sqrt{5}\over5+\sqrt{2}\]
Step 1 multiply both the numerator by the conjugate of the denominator. In this problem the conjugate is:\[5-\sqrt{2}\] so your problem would now look like this:\[\sqrt{5}(5-\sqrt{2})\over(5+\sqrt{2}) (5-\sqrt{2}\] do you follow so far?
yess i do
r u there
Our fraction now becomes:\[5\sqrt{5}-\sqrt{10}\over25-2\] or\[\sqrt{5}(5-\sqrt{2})\over23\]\[2.236(5-1.414)\over23\]\[(2.236)(3.585)\over23\]\[8.01606\over23\] .3485
thnk u theres another problem
You could, rather than rationalize the denominator just use your calculator. Lets do that on the second one.
ok thnks
\[2-\sqrt{3}\over-2-\sqrt{5}\] \[2-1.732\over-2-2.236\]\[.268\over-4.236\] -.06326
There is an error somewhere, the answer is negative, but larger negative than that!
