don't you multiply \(\bf{7*10*8}\) and add the exponents?

Okay so if we do that then we will have \[7 \times 10 \times 8 = 560\] But how do i add the exponents?
Mehek14
  • Mehek14
\(v^3+v^5+v^3=3+5+3=11\\v^11\\u^3+u^1\\3+1=4\\u^4\)
Mehek14
  • Mehek14
\(v^3+v^5+v^3=v^{11}\)
Mehek14
  • Mehek14
add numbers keep same variable
calculusxy
  • calculusxy
So would my answer be 560v^11v^4 ?

@Hero

  • Hero
You wrote two v's your u variable is missing.
calculusxy
  • calculusxy
Sorry i meant 560v^11u^4
calculusxy
  • calculusxy
Am I correct?
calculusxy
  • calculusxy
I really need help on this.
calculusxy

@zzr0ck3r
Hero
  • Hero
Correct, sorry.
calculusxy
  • calculusxy
Okay thank you. So I am going to do the next one: \[\large 9xy^2 \times 9x^5y^2\]
calculusxy
  • calculusxy
\[\large 9x^1y^2 \times 9x^5y^2 = 81x^6y^4\]
calculusxy
  • calculusxy
@Hero
AbdullahM
  • AbdullahM
correct
calculusxy
  • calculusxy
Can i check more with you?
AbdullahM
  • AbdullahM
absolutely :)
calculusxy
  • calculusxy
\[6m^3n^3 \times 8m^2n^3 = 48m^5n^6\]
AbdullahM
  • AbdullahM
correct again :)
calculusxy
  • calculusxy
\[6x^2 \times 6x^3y^4 = 36x^5y^4\]
AbdullahM
  • AbdullahM
correct :)
calculusxy
  • calculusxy
\[7u^2v^5 \times 9uv^3 = 63u^3v^8\]
AbdullahM
  • AbdullahM
correct (:
calculusxy
  • calculusxy
\[uv \times 4uv^5 = 4u^2v^6\]
AbdullahM
  • AbdullahM
and correct once again c:
calculusxy
  • calculusxy
\[10xy^3 \times 8x^5y^3 = 80x^6y^6\]
AbdullahM
  • AbdullahM
correct
calculusxy
  • calculusxy
\[3u^4v^5 \times 7u^2v^3 = 21u^6v^8\]
AbdullahM
  • AbdullahM
correct :)
calculusxy

\[(2x^2)^2 = 2x^4\]
calculusxy
  • calculusxy
\[(p^4)^4 = p^16\]
calculusxy
  • calculusxy
\[(2x^2)^2 = 2x^4\]
AbdullahM
  • AbdullahM
uh-oh
calculusxy
  • calculusxy
just in case if you want to ask for (p^4)^4, my answer is p^16
AbdullahM
  • AbdullahM
Use the formula \(\bf\Huge (ab)^m = a^mb^m\)
AbdullahM
  • AbdullahM
That one is correct For that question, in latex you have to put p^{16}
calculusxy
  • calculusxy
\[p^{16}\]
AbdullahM
  • AbdullahM
But \(\bf\Large (2x^2)^2 \neq 2x^4\)
AbdullahM
  • AbdullahM
So use the formula I gave you :)
calculusxy
  • calculusxy
\[\large 2^2 \times (x^2)^2\]
calculusxy
  • calculusxy
\[4 \times x^4\] ?
AbdullahM
  • AbdullahM
correct :D
calculusxy
  • calculusxy
@AbdullahM I juts want to make sure a couple more if u have no problem :)
AbdullahM
  • AbdullahM
I would love to :)
calculusxy
  • calculusxy
thank you!
calculusxy
  • calculusxy
\[(k^3)^4\]
calculusxy
  • calculusxy
= \[k^12 \]
AbdullahM
  • AbdullahM
correct :)
calculusxy
  • calculusxy
sorry i forgot the latex
calculusxy
  • calculusxy
\[k^{12}\]
calculusxy
  • calculusxy
OH wait..
calculusxy
  • calculusxy
\[7^2 \times k^2 = 12 \times k^2\]
calculusxy
  • calculusxy
i meant 14
calculusxy
  • calculusxy
\[\large 14 \times k^2\]
AbdullahM
  • AbdullahM
So the question is \(\bf\Large 7^2 \times k^2 = 14 \times k^2\)
calculusxy
  • calculusxy
yes am i correct?
AbdullahM
  • AbdullahM
No... \(\bf\Large 7^2 = 7\times 7\neq 2\times 7\)
calculusxy
  • calculusxy
oh my god.. silly mistake ! sorry i meant to say 49 x k^2
AbdullahM
  • AbdullahM
good :)
calculusxy
  • calculusxy
\[\large (2b^2)^4 = 2^4 \times (b^2)^4 = 16b^8 \]
calculusxy
  • calculusxy
sorry but can u just say correct or incorrect really quickly? i need to go.
AbdullahM
  • AbdullahM
correct
AbdullahM
  • AbdullahM
sorry, I was looking at another tab :p
calculusxy
  • calculusxy
thank you so much for ur help! i truly appreciate it :)
calculusxy
  • calculusxy
sorry one quick question
AbdullahM
  • AbdullahM
sure :D
calculusxy
  • calculusxy
\[2n^4 \times 5n^4 = 10n^8\]
calculusxy
  • calculusxy
and \[2n^4 \times 6n^4 = 12n^8 \]
calculusxy
  • calculusxy
those are basically the same
AbdullahM
  • AbdullahM
correct for both :D
