Quick math help please!!!
What is log2 (3) + log2 (x)=3?

Also how can the properties of exponents help solve logarithmic equations?

I'm stumped on these two and I've been trying to figure them out for so long.

raden · Answer

use the property : 
loga (m) + loga (n) = loga (mn)

so that would be log2 (3x). What do I do next?

raden · Answer

yeah, then the equation becomes
 log2 (3x) = 3, right ?

jcmbourque19 · Answer

I still don't get how to solve... really don't understand this

raden · Answer

log2 (3x) = 3

we can convert it into exponent form :
2^3 = 3x
then solve for x

raden · Answer

got it ?

8=3x
so x=8/3 
Thank you so much!!!

raden · Answer

yes, that's right.
