i need to solve or what?
jdoe0001
  • jdoe0001
nope, just find another equation that is the same, just expanded differently or factored
anonymous
  • anonymous
factored? :/
jdoe0001
  • jdoe0001
hmm can you post a quick screenshot of the material?

@EmilyF03 check your phone, chances are it does have a camera, also your computer may have one, if it's on paper, just shoot it there if it's on the screen, just use the PrinScreen button

ok, finally
jim_thompson5910
  • jim_thompson5910
the \(\Large (1.8)^{2x}\) can be turned into \(\large (1.8^2)^{x}\) |dw:1437176410031:dw|
jim_thompson5910
  • jim_thompson5910
what is 1.8^2 equal to?
anonymous
  • anonymous
3.24?
jim_thompson5910
  • jim_thompson5910
so \[\Large 4(1.8)^{2x} = 4(3.24)^x\]
jim_thompson5910
  • jim_thompson5910
I used the rule \[\Large x^{y*z} = (x^y)^z\]

  • anonymous
oh okay, so the answer its A?

  • jim_thompson5910
yeah
