okay for y^2)^5 use this rule \[X^m)^n = x^{m*n}\]
anonymous
  • anonymous
do you know this rule?
anonymous
  • anonymous
yes i know this rule somewhat lol im bad at math so
anonymous
  • anonymous
well y^2)^5 uses this rule, so multiply 5 by 2 you get y^10
anonymous
  • anonymous
now you have \[y^{10} * y^8\] and use this rule----> \[y^m * y^n = y^{m+n}\]
anonymous
  • anonymous
and voila the answer
anonymous
  • anonymous
so the answer is 7a^4b^3
anonymous
  • anonymous
...what?
anonymous
  • anonymous
where did you get a and b from? the wuestion only has y.
anonymous
  • anonymous
sorry i was looking at a different question
anonymous
  • anonymous
..lol i was like totally flabbergasted, i was like what just happened? anyway do you know the answer?
anonymous
  • anonymous
a. y^23 b. y^18 c. (y)^40 d. y^5
anonymous
  • anonymous
those are the choices
anonymous
  • anonymous
i think it is b
anonymous
  • anonymous
yyup ur correct
anonymous

now can u help with another problem
anonymous
  • anonymous

Find the product. (-3ab2)3
anonymous
  • anonymous
what is it?
anonymous
  • anonymous
Find the product. (-3ab^2)^3 my choices are a.) 27ab b.) -23a^2b^2 c.) -9a^3b^5 d.) -27a^3b^6
anonymous
  • anonymous
simple everything inside the brackets are going to be affected nby the exponent first step: what is -3^3?
anonymous
  • anonymous
-27
anonymous
  • anonymous
good then what is a^3... well that's actually just a^3
anonymous
  • anonymous
finally what b^2)^3
anonymous
  • anonymous
b^6
anonymous
  • anonymous
now put it together
anonymous
  • anonymous
-27a^3b^6
anonymous
  • anonymous
yup :)
anonymous
  • anonymous
willing to help me with a few more??????
anonymous
  • anonymous
if not thats ok but just asking
anonymous
  • anonymous
no problem

Find the product (a2b3)4
anonymous
  • anonymous
(a^2b^3)^4
anonymous
  • anonymous
same thing as before whats a^2)^4
anonymous
  • anonymous
a^8 ?
anonymous
  • anonymous
yup and b^3)^4?
anonymous
  • anonymous
b^12
anonymous
  • anonymous
yup and put it together
anonymous
  • anonymous
yay i was right XD lol i had that the first time i just wasnt sure

exactly its not so bad after a couple of problems
anonymous
  • anonymous
one more
anonymous
  • anonymous
okay
anonymous
  • anonymous
hit me
anonymous
  • anonymous
(n^3)^2 · (n^5)^4 i got n^26
anonymous
  • anonymous
that's right! :)
anonymous
  • anonymous
XD yay really
anonymous
  • anonymous
:D im glad you got the hang of it, anymore you want to try?
