Question

Simplify the radical expression (see comment).

Answer 1

\[\Huge3\sqrt[3]{375}\]

Answer 2

Also, \[\Huge\sqrt{10}\left( 4-\sqrt{5} \right)+\sqrt{8} \left( \sqrt{5} + 2\right)\]

Answer 3

\[15\sqrt[3]{3}\]

Answer 4

♥ Can you get the next one for me? :3

Answer 5

yep, gimme a minute :)

Answer 6

I have a few more, if that's not pushing it :p

Answer 7

\[6\sqrt{10}+9\sqrt{2}\]

Answer 8

Ask away! :)

Answer 9

o.o 6sqrt10+9sqrt2 isn't one of the answers

Answer 10

whaaat?

Answer 11

\[\large\sqrt{10}\left( 4-\sqrt{5} \right)+\sqrt{8} \left( \sqrt{5} + 2\right)\]distribute into the parenthesis:\[\large4\sqrt{10}-\sqrt{50}+\sqrt{40}+2\sqrt{8}\]simplify the radicals:\[\large4\sqrt{10}-5\sqrt{2}+2\sqrt{10}+4\sqrt{2}\]add/subtract:\[\huge6\sqrt{10}-\sqrt{2}\]

Answer 12

closest to that is 6sqrt10-sqrt2

Answer 13

ty yummy. lal. you too mad :3

Answer 14

try working these out poopsie..you need to learn how to do these, not simply be given the answers

Answer 15

if that's the case, dont bother posting your questions just put them into http://www.wolframalpha.com/

Answer 16

Well, I kinda get how to do it from what you're saying there. How about I try to work one out and you check my answer? :3

Answer 17

yes that's better

Answer 18

and again...if al you need to do is check your answer, just put it into https://www.wolframalpha.com/ and itll give you the answer in seconds

Answer 19

\[\left( 6+3\sqrt{2} \right)\left( 5-\sqrt{2} \right)\]

============

\[24+9\sqrt{2}\]

Answer 20

I've tried wolframalpha, and I hated it. ._.

Answer 21

@yummydum

Answer 22

\[\left( 6+3\sqrt{2} \right)\left( 5-\sqrt{2} \right)\]FOIL and simplify:\[30-6\sqrt{2}+15\sqrt{2}-3\sqrt{4}\]\[30-9\sqrt{2}-3(2)\]\[30-9\sqrt{2}-6\]\[24-9\sqrt{2}~\checkmark\]\[\huge\ddot\smile\]

Answer 23

Now, for (7+√3)(7-√3) it would be 46, right?

Answer 24

\[(7+√3)(7-√3)\]FOIL and simplify:\[49-7\sqrt{3}+7\sqrt{3}-\sqrt{9}\]\[49-3\]\[46~~\checkmark\]\[\large\ddot\smile\]

Answer 25

Quick question, √125=? I'm tired and confused e_o

Answer 26

5√5.

Answer 27

I couldn't think straight.

Answer 28

yup :D

Answer 29

lol no problem...get up and take a 10 second walk :) itll freshen you up (IF AND ONLY IF YOU DONT HAVE ADHD)

Answer 30

does 5√5*6√5=30√5?

Answer 31

yes :)

Answer 32

try mathway.com

Answer 33

Now, here's one that I don't need help with the problem, but with a question related to the problem.

Find the perimeter of a rectangular object which has a length of √180 feet and a width of √125 feet.

I know that this is 5√5*6√5, but what is an Object found in a house/school that has these dimensions?

Answer 34

@yummydum got any ideas?

Answer 35

well \(\sqrt{180}ft\) is \(\approx13.416ft\) and \(\sqrt{125}ft\) is \(\approx11.180ft\)
so something that is \(11ft\times 13ft\) ....umm...a rug? :)
