solve log2(35x)-log2(7)=3

Nnesha (nnesha):

apply quotient property \[\huge\rm log_b x \color{red}{-} \log_b y = \log_b \frac{ x }{ y }\] if there is negative sign you can change that to division subtraction ---->division addition .-----> multiplication

OpenStudy (anonymous):

ya thats as far as I got @Nnesha

OpenStudy (anonymous):

do you times the 3 by the 7?

Nnesha (nnesha):

\[\huge\rm log_2 ( 35x) - \log_2 (7) =3\] after quotient property change log to exponential form

OpenStudy (anonymous):

ok so 2^3=35x/7

Nnesha (nnesha):

yep!!

OpenStudy (anonymous):

so after all the calculations it would be 1.6?

Nnesha (nnesha):

yep that's right

OpenStudy (anonymous):

wow im making these a lot harder than they really are haha. thanks again.

Nnesha (nnesha):

yep these type of question r very easy
