  1. last step on #1  it's should be +

    2nd to the last step for #2    :  didn't inverse the value

    didn't see anythign on #3

    2nd step of #4  can't change both the x and y when only y's exp is negative

    it's for your own good to know how to do these in the long run, so try to take a stab at it first next time and ask when you're stumped or need to check your answer


  2. http://info.means.it

    you can get much information in this website, If you will check anyone blue link in website.


  3. I'll cheat too.  

    In the first problem a^2-16/a-4 (or something like that) is a+4.  Remember the (a^2-b^2) factoring routine.

      

    Just take a pencil and follow along with the problems. You should be able to stumble across the errors.

  4. all wrong except last as far as i can see...

    1. first move is wrong...x top and bottom of fraction by 16...16Xa^2/16 is not equal to a^2/16!

    2.to divide fractions you X by inverse...so step 4 is incorrect!

    3.same as before^^...step 3

    4. correct i think
