Check this.? Im not very good with logarithms and i watched a video and it said to do it like this but im not sure
Log\/2(3)+log\/2(x)=3
then cancel out the logs as they are the same base so,
3+x=3
3 3
x=0???

Best ResponseYou've already chosen the best response.3i mean equation \[\log_2(3)+\log_2 x=3\] like this OR

Best ResponseYou've already chosen the best response.3\[\frac{ \log_2 3 }{ \log_2 x} =3\]

Best ResponseYou've already chosen the best response.3maybe or maybe division hmm which one is correct ? graysongraddyLOL

Best ResponseYou've already chosen the best response.3quotient rule\[\large\rm log_b x  \log_b y = \log_b \frac{ x }{ y}\] to condense you can change subtraction to division product rule \[\large\rm log_b x + \log_b y = \log_b( x \times y )\] addition > multiplication power rule \[\large\rm log_b x^y = y \log_b x\]

Best ResponseYou've already chosen the best response.3quotient rule\[\large\rm\color{reD}{ log_b x  \log_b y = \log_b \frac{ x }{ y}}\] to condense you can change subtraction to division product rule \[\large\rm \color{reD}{log_b x + \log_b y = \log_b( x \times y )}\] addition > multiplication power rule \[\large\rm \color{Red}{log_b x^y = y \log_b x}\] you don't need ^power rule for this e quation we should apply it when there is a number at front of log

Best ResponseYou've already chosen the best response.0so with the equation that i am using, How do i get a Log on the other side of the equal sign.?

Nnesha

Best ResponseYou've already chosen the best response.3alright we need to apply product rule which is \[\large\rm \color{reD}{log_b x + \log_b y = \log_b( x \times y )}\] log_b same base so take it out and multiply x y \[\log_b x+ \log_b y\] \[\log_b (x \times y)\]

Best ResponseYou've already chosen the best response.0So multiply 3 and x.?

Best ResponseYou've already chosen the best response.3\[\huge\rm log_2(3)+\log_2 x=3\] like this OR yes right!!

Nnesha

Best ResponseYou've already chosen the best response.3that's how we should condense log equations \[\huge\rm log_2 (3 \times x)=3\] now we should convert log to exponential form

Best ResponseYou've already chosen the best response.3well you will see how easy it's just have to move that variables around

Best ResponseYou've already chosen the best response.3we need to convert to exponential there shouldn't be an log b=2 how would write 2 with 3 exponent ?

Best ResponseYou've already chosen the best response.3\[\huge\rm log_3 (4)  \log_3 (y) = 2\] look at the log properties

anonymous

Best ResponseYou've already chosen the best response.0So id use the first one right.?

anonymous

Best ResponseYou've already chosen the best response.0then it would go to \[\log_{3}(4 \div x)=3\]

Best ResponseYou've already chosen the best response.3it's y not x but it's okay :P

Best ResponseYou've already chosen the best response.3i'm not gonna take off points like teachers do lol

anonymous

Best ResponseYou've already chosen the best response.0So it would go to \[3^{4}=3x\]

anonymous

Best ResponseYou've already chosen the best response.0Where did i go wrong.?

Nnesha

Best ResponseYou've already chosen the best response.3the number which is opposite of the log supposed to be the exponent of base \[\log_3 ( \frac{ 4 }{ x }) =2\] and btw it's equal to 2 i would take off points for this mistake

anonymous

Best ResponseYou've already chosen the best response.0okay so it would go to \[\frac{ 4 }{ x } = 2x \]

Best ResponseYou've already chosen the best response.3how did you get two x's ?

anonymous

Best ResponseYou've already chosen the best response.0wait it would just be 2 on the right side

anonymous

Best ResponseYou've already chosen the best response.0then i multiply 4 from the left side to get 8 on the right side so x=8.?

Best ResponseYou've already chosen the best response.3here is the example to convert log to exponential form \[\huge\rm log_\color{ReD}{b} x = \color{blue}{y}\] b is base \[\huge\rm \color{ReD}{b}^\color{blue}{y} =x\]

Nnesha

Best ResponseYou've already chosen the best response.3not really hmm it's 4/x so that would stay same at right side \[3^2=\frac{ 4 }{ x }\]now solve for x
