hw #7-3 Properties of Powers & Exponents
Note: We are skipping scientific notation (section 7-2) and will come back to it SOON... (I could tell that you were VERY concerned!)
I was just wondering if there were any chances for extra credit, just because i wanted to improve my grade a little bit. It would be really helpful knowing that there was a little more slack in my grade :)
That's a great idea!!!! I have a question: can u give test corrections on grades 97 and up? And also, when are we going to have our notebook check? And, how much are they worth????
For #25 on pg 417, I don't understand how the book got 1/9n. So far, I have 1/9 over n, and I don't know what to do.. Multiple both sides by n? But then answer would become 1/9, right?
Waiitttttt.. Nevermind! I figured it out! You DO multiply both sides by n or y or whatever the variable is. Then the answer would become right.. I just got mixed up with multiplying the bottom number by n too, but its only the top fraction:)
Yup! I got it! My dad helped me! I was sure how to figure out problems like (for example) 4s^3/1/2s^2, but then you could break them up like this: (4s^3/1)*(2s^2/1) :D
But one thing I think we should review is Scientific Notation.. Although you said we are postponing that there was some of it in the homework.

ReplyDeleteSo much homework.. I didn't do the 7-1 homework because you told us not to.. Now I have 2 ALGEBRA DAYS WORTH OF HOMEWORK!!!!
ReplyDeleteyou just wanted to say you got 97 Tyler
ReplyDeleteI GOT 100%!!!!
ReplyDeleteYAY!!!!!

ReplyDeleteHelp!!
I have the same problem for #27.. I have 3/x^2 over y and I don't know how to get rid of the y to get the answer the book has!!

ReplyDeleteNevermind that above.. I still don't get it.
ReplyDeleteD:
Because if its a fraction over a fraction what do you multiply the denominator's reciprocal by?!
Why is 29 1/c^5d^7?
ReplyDeleteI can't figure out #31 either! What I have so far is 8 over 2/x^3...
ReplyDeleteI guess this is why we why we have classes... I'll see y'all tomorrow... we'll go over it problem by problem, ok?
ReplyDeleteThe surest way to figure things out is to break everything apart into it's own fraction, and then put it back together again.
Yup! I got it! My dad helped me! I was sure how to figure out problems like (for example) 4s^3/1/2s^2, but then you could break them up like this:

Hooray for dads!!
ReplyDeleteAlthough they follow the same basic "POWER" rules, you can ignore any SciNot problems that sneak into the homework for now.
