log base 3 of radical 27 is basicaly saying 3 to the what power = sqrt(27)
anonymous
  • anonymous
and i don't understand logs in general
anonymous
  • anonymous
but theres a 2 in front..
anonymous
  • anonymous
you multiply by two after you get the first part
anonymous
  • anonymous
its just multiplication in front
anonymous
  • anonymous
do u mind drawing this out ? sorry I'm really stupid :(

\[2 log_{3} (\sqrt {27})\] x=log y to the base b means b^x=y
anonymous
  • anonymous
we actually just did this stuff today and yesterday in math class
anonymous
  • anonymous
uh oh...maybe you're in my math class lol ...
ash2326
  • ash2326
and we have the property c log y= log y(^c)
anonymous
  • anonymous
lol, do you have algebra 2 im guessing?
anonymous
  • anonymous
nope...im still very confused about the 2 in front though...this whole thing makes no sense to me
anonymous
  • anonymous
the two in front is just multiplication, its like y = 2x, the two is multiplied
ash2326
  • ash2326
now \( 2 \log_{3} (\sqrt{27})\) \(\log_{3}{(\sqrt{27})}^2\) \(\log_{3} 27\) we know that 3^3=27 so it's \(\log_{3} 27=3\)

anonymous
  • anonymous
i am literally so confused
anonymous
  • anonymous
well, whatever he is doing is right.
