Ok, let me see what I can do. I'm going to help you with these step by step okay?

  • Chrisg094
Alright Thanks

So is the problem for the first one, 21x^8-35x^7+35x^5+49x^3+3x^2/7x^5?
Chrisg094
  • Chrisg094
correct.

  • anonymous
First thing I would do is combine our like terms by adding.
Chrisg094
  • Chrisg094
I was going to do that, but I don't think there are any because they all have different exponents.
anonymous
  • anonymous
They have to have the same base in order to add them. They all have the same base of X right?
Chrisg094
  • Chrisg094
oh, yeah the do has
Chrisg094
  • Chrisg094
have the same base
Chrisg094
  • Chrisg094
so that means the exponents will have to be added right?
anonymous
  • anonymous
yes
anonymous
  • anonymous
now, x is always an understood 1 right?
Chrisg094
  • Chrisg094
yes.

  • Chrisg094
that is what I got but i don't know what to do next
anonymous
  • anonymous
Ok, your exponent is right, but I'm still trying to figure out what our base number is. I'll be right back once I do. :)
Chrisg094
  • Chrisg094
ok
anonymous
  • anonymous
Let me see how you got 73 as your base so I can see what you did.
Chrisg094
  • Chrisg094
21-35+35+49+3
Chrisg094
  • Chrisg094
then for the exponents 8-7+5+3+2
anonymous
  • anonymous
ok, let me show you what I did. I would think that it's not 21-35, I would think they are wanting you to do 21x(-35). That's what I was taught.
anonymous
  • anonymous
so with that being said what I would do is 21x(-35)+3+49+3 which gives us -680. We aren't done just yet
anonymous
  • anonymous
now we have to do -680^25 which gives us -6.497148866^70, but we still aren't done. It seems like a crazy number right?
Chrisg094
  • Chrisg094
yeah
anonymous
  • anonymous
We still have to work out 7x^5 power. So we know that is going to be 16807
Chrisg094
  • Chrisg094
actually that exponent, doesn't it belong to the x and not the base
anonymous
  • anonymous
Ok, I think I've messed up! Let me try your 73^25 and see what happens.
Chrisg094
  • Chrisg094
because from what I recall its 7 times x^5
anonymous
  • anonymous
Ok, I thought I had this one. I'll help you find someone who can do this. What grade is this?
