QuestionFind logbAB\log_{b} \frac{A}{B} given logbA=2\log_{b} A=2 and logbB=4\log_{b} B=-4.

Studdy Solution

STEP 1

Assumptions1. logbA=\log{b} A= . logbB=4\log{b} B=-4
3. We are looking for the value of logbAB\log{b} \frac{A}{B}

STEP 2

We can use the property of logarithms that states logbAB=logbAlogbB\log{b} \frac{A}{B} = \log{b} A - \log{b} B.
logbAB=logbAlogbB\log{b} \frac{A}{B} = \log{b} A - \log{b} B

STEP 3

Now, we can substitute the given values of logbA\log{b} A and logbB\log{b} B into the equation.
logbAB=2()\log{b} \frac{A}{B} =2 - (-)

STEP 4

Calculate the value of logbAB\log{b} \frac{A}{B}.
logbAB=2(4)=6\log{b} \frac{A}{B} =2 - (-4) =6So, the value of logbAB\log{b} \frac{A}{B} is6.
