Question

PLEASE HELP 

log33 + log3x = 5 ??

whpalmer4 · Answer

Is that $$\log_{3}3+\log_{3}x=5$$?

anonymous · Answer

yes

whpalmer4 · Answer

Adding  logs of two numbers is the same as taking the log of the product so we can rewrite that as $$\log(3x)=5$$
Do you know how to solve that?

whpalmer4 · Answer

We could also notice that log base 3 of 3 =1 because 3^1=3

anonymous · Answer

No, I'm terrible at these :/

whpalmer4 · Answer

If we go that route, $$\log_{3}x=4$$

anonymous · Answer

lol
from conic sections to logs in one day. what is next? riemann sums? baye's formula?

anonymous · Answer

that's not helping -___- haha

whpalmer4 · Answer

Let's go that latter route.  The log base 3 of x means find the number where 3^number gives you x.  We know the number is 4, so $3^4=x$

whpalmer4 · Answer

$$x=3^4=3*3*3*3=$$

So the final answer would be 81 @whpalmer4
