Notes
 |
| 13.1 problem 1 clarification on the table. Notice that we need the totals on the second column, not the number of dams and the number of sires separately. It makes the pattern make more sense. |
 |
| 13.1 Problem 2: This is all of the information you need to completely answer the question. |
 |
| The parentheses confused several people so we worked some problem to help with the difference in parentheses and negative sign position. |
 |
| A few more examples for 13.1 problem 2 |
 |
| Use #3 to answer #5 and #6. |
im having problems with problem three in 13.1 i still dont understand it...
ReplyDeleteHave you written each one out as multiplication problem?
DeleteSay if you had 3 to the second power and 4 to the second power, would you be able to simplify those two even if they don't have the same base?
ReplyDeleteAlso, how am my supposed to simplify something like 12x to the fourth power (with) y to the fifth power divided by 2xy to the third power?
The first one is as simplified as you can get it using exponent rules.
ReplyDeleteFor the second one, factor everything-even the 12- and see what divides out to one (cancels because they are the same on the top and bottom).
Then I can't really do anything about it? Just leave the question blank?
ReplyDelete(2nd) And I'm confused on how exactly how to do that.
What do the instructions on that one say? Simplify, write as a product, or evaluate?
ReplyDeleteI am not sure how this will look typed on a comment.
12x^4y^5=2×2×3×xxxxyyyyy
2xy^3 = 2xyyy
The numerator and denominator have a 2, an x, and 3y's in common so those become 1 which in multiplication means thye don't change anything. The answer is what is left.
(1st)Just to simplify each expression. (I used a "for instance" example when I told you that but that's pretty close.)
ReplyDelete(2nd)Wait, so you're allowed to do it like that? (2 and 2 and 3 all multiplied together?)
But I understand now where you're coming from. This whole business kind of gave me a headache today. But now I'm sort of understanding. Thank you, Ms.Lowery.
Muliply it out to one answer since taht doesn't mention exponents.
ReplyDeleteAnd yep, you can use prime factorization to divide anytime. Today was kinad heavy, but I hope it helped. I am glad you are getting it.
I don't understand 3.4 problem 1 number 2.how do we put a, b, and c to the 2nd power?
ReplyDeleteI only have 13.1 and 13.2 at home with me. We will get to 13.3 and 13.4 next week. I am proud that you want to work ahead but wait for now.
DeleteI meant 13.2 problem 1 question 2.
ReplyDeleteThat is the one where you rewrite the previous problem in base 2, not squared. The problem in 13.1 about the dogs should help since it is also in base 2.
Deleteon 13.2 problem 2 question 3 me and jhase do not understand that? what does it mean by relationships i dont notice any relationships
ReplyDeleteok i got it
