Answer 4

You shouldn't ask for medals. Medals are rewards for doing something good, nice, and/or helpful. Try helping some people with their questions, and maybe, just maybe, you'll get some medals. :)

Answer 5

yeah, not good idea to pull user in by using medal.

Answer 6

@OrangeMaster Just for your post, you get a medal :)

Answer 7

"my math test"

you shouldn't use these words if you really want help... this is against rule lol...

Answer 8

and well most people dont pay attention unless i put that. ok its not a real real test really tho

Answer 9

try to turn square roots into exponents.

Answer 10

\(\sqrt{a} = a^{\frac{1}{2}}\)

Answer 11

and i didnt know that either.....its math that i dont understand it i contacted my teacher he said that open study and they can help and i have been using the book i need steps not answers now if people can not help me (not being rude being real) please do not wait my time or anyone else

Answer 12

waist

Answer 13

you mean waste?

Answer 14

so you don't know exponents yet?

Answer 15

yes sorry its late and im just not in the mood to use right grammar... ok i do understand them i just dont understand how to start this out really

Answer 16

do you know exponent properties?
for example:
\(\sqrt{a^3} = a^\frac{3}{2}\)
and \(\dfrac{a^m}{a^n} = a^{m-n}\)

Answer 17

that looks familiar actually and so all i would have to do is add the questions numbers in were the other things r ?

Answer 18

thanks still!

Answer 19

I'm sorry. you still need help?

so you just turn square root into exponent.

\(\dfrac{\sqrt{k^5}}{5\sqrt{9\cdot2\cdot k}} = \dfrac{k^{\frac{5}{2}}}{5\cdot3(2k)^{\frac{1}{2}}}\)

Answer 20

now you just need to subtract exponents

Answer 21

do you understand what is going on in denominator?

Answer 22

oh i see and no but thank you for putting it in i really just needed the rule of it. and kinda when i look at it i see

Answer 23

i can give you explanation for denominator.

Answer 24

could you thanks id like to wright that down too

Answer 25

could you show me please

Answer 26

ok, so 18 = 9⋅2, right?
so \(\sqrt{18} = \sqrt{9\cdot2} = \sqrt{9}\sqrt{2} = 3\sqrt{2}\)

Answer 27

is that clear?

Answer 28

ohhh yes thanks sooo much!!

Answer 29

makes more since lol thanks! i have to go to bed but thank you so much!

Answer 30

@geerky\[5/2 -1/2 = 2\]42 Ok so i got the answer

Answer 31

@geerky42

Answer 32

yeah, since exponent is positive, k should be in numerator with an exponent of 2.

So your answer should be like this:
\(\dfrac{k^2}{15\sqrt{2}}\)

Answer 33

yay!! i got it right then thank!
