Great! Thanks for your help. Is there a rule/title for the process of converting from the original problem to the way that you split it (separating the base ten numbers)? Also, am I calling those the right thing? Base ten numbers? Should they be called, "base ten exponents"? The answer I got is...

1. Homework Statement (2.5 x 10^24)(4.5 x 10^-9) / (3 x 10^4) Homework EquationsThe Attempt at a Solution [/B] I know that when multiplying base ten numbers with exponents you add the exponents (ie: 10^2 x 10^3 = 10^5) ad that when dividing, the exponents are subtracted. I'm not sure what...

Dreams are so interesting! I've been told I need to see Inception. I'll get on it! Keeping a dream logbook sounds like a great idea. I've tried to do it in the past but putting off writing a dream down for even an hour afterwards is tough-- it's crazy how quickly our memories of dreams...

How come some mornings we wake up and don't remember our dreams but other mornings we remember multiple dreams? The past five days I have woken up and remembered my dreams and I'm wondering if I should get a dream catcher... :) Thanks for your help!

The hair on my head grows longer and longer while other hairs, like arm hair, only grow to a much shorter length. Why do certain hairs on the body grow only to certain lengths? How do the cells know when to stop? Thank you! →

On Earth, fire needs oxygen. If space has no oxygen, how does the sun continue to burn? Thanks! :) Ω

With the leaves starting to change I have been wondering what causes the more dramatic colors verses the more dull leaf colors. I have been told that sunny days and cool nights is the best environment for good autumn colors. If this is true, why does that create the nice colors? Thanks!

The last few times I've seen a rainbow I've wondered this... Is the arch of a rainbow always the same? As in... Does the rainbow's radius ever change? Also, why are the width of the colors and the rainbow itself always the same? I was also talking about this with a few elementary school...

Hahaha That's awesome. Well said. Toph... I understand and can relate to your situation, but I honestly think that you need to really try to discuss you concerns with your boyfriend, especially since you feel so strongly about your views. If he really loves you (which it seems like he does!)...

Yes! I have an account! :) Thanks for all the congrats. Greg is awesome! :)

That. Is. AWESOME! Hip Hip Hooray!

So I've been hanging out with this adorable dog (small labradoodle) of the family that I nanny for and she has got me asking a lot of dog-related questions. Right now what's on my mind is this... Why do dogs (and other animals?) roll in stinky smelling things like dead animal residue? Are...

Wow! Great info and good follow-up questions Greg. Thanks! I love thunderstorms and would love to witness a snow thunderstorm!

A hole was found in a wall at the nudist camp. The police are looking into it...

Teacher: "Josephine, give me a sentence beginning with I." Josephine: "I is ..." Teacher: "No, Josephine. It's always 'I am...' " Josephine: "OK. I am the ninth letter of the alphabet." Also very funny! hahaha... I definitely will tell my teacher friends this one. :)
