Question

cowboy · Answer

$$3\sqrt{3}$$ is my answer.

cowboy · Answer

I mean 5^3

anonymous · Answer

can do a^2 + b^2 = c^2

anonymous · Answer

$$\text{simplify }\sqrt{725}$$

cowboy · Answer

Ah, 27?

cowboy · Answer

27^2 correct?

anonymous · Answer

not quite
pull out any perfect square factors
25 is a square factor of 725
$$\sqrt{25}\sqrt{29}$$
$$5\sqrt{29}$$

cowboy · Answer

I honestly didn't see what you did there.

anonymous · Answer

with the radical? or?

anonymous · Answer

sorry I'm sleepy and will be getting less and less coherent =P

cowboy · Answer

Same here, too sleepy. Umm start back at the beginning. What did you do with a^2 + b^2 = c^2 exactly.

anonymous · Answer

10^2 + 25^2

anonymous · Answer

that equals the c^2

cowboy · Answer

Then, it goes to 725^2? thats where I got lost.

anonymous · Answer

and we are trying to find the c that when multiplied equaled 725

anonymous · Answer

so you get the squareroot of 725 and that is your c

cowboy · Answer

26.9 or 27...

anonymous · Answer

are you supposed to submit it in rounded decimal form?

anonymous · Answer

because technically that isn't the right answer but it is rounded close to the right answer

cowboy · Answer

I don't think I have to. But I would rather have it rounded.

cowboy · Answer

Well that's what my calculator gave me.

anonymous · Answer

it's a radical number it goes on and on

anonymous · Answer

which is why we show it as $$5\sqrt{29}$$

cowboy · Answer

Huh, that really doesn't make any sense.

cowboy · Answer

Just feels like people randomly make up this stuff >.<

anonymous · Answer

haha yah, some of it is pretty abstract

cowboy · Answer

I was good at math. Until they mixed the alphabet in with it.

anonymous · Answer

=P it comes together after awhile.

cowboy · Answer

I suppose. Some of it. I never really "remember" stuff though.

anonymous · Answer

repetition was the key for me. I've had trouble remembering certain things too.

cowboy · Answer

Like the problems with 50 steps >.<

anonymous · Answer

lol yeah
