whatevs Group Title Simplify 7 log3 k + 6 log3 m – 9 log3 n? can someone show the steps on how you do this? 2 years ago 2 years ago

A. log3 B. 4 log3 C. log3 D. 4 log3 (k + m – n)

Let's first recall a couple of log identities: $\left[\begin{matrix}\text{First} & x*\log(y) = \log(y^x) \\ \text{Second }& \log(x*y) = \log(x) + \log(y) \\\text{Third} & \log({x \over y}) = \log(x) - \log(y) \end{matrix}\right]$From the First identity:$\log(k^7) + \log(m^6) - \log(n^9)$From the Second and Third Identity$\log({k^7 m^6 \over n^9})$

hey eashmore, could you look at problem D on greenday's A 1100 kg car is traveling at 24 m/s. post?

4. whatevs Group Title

that is choice C, but it has 3with the log?

5. eashmore Group Title

Same difference. I omitted the base for ease of typing it up. Remember these identities only apply when the base is the same.

6. do_0b.ie Group Title

so are you master of the logarithms now?

7. whatevs Group Title

not totally..lol

8. do_0b.ie Group Title

keep it up.. have fun

9. whatevs Group Title

lol..do you know a good website to graph functions?

What is the function? I'll type it in so you have an idea of how to type things in.

thanks eashmore for the physics help

14. whatevs Group Title

f(x) = log0.3 x

15. eashmore Group Title

A base of 0.3?

16. eashmore Group Title
17. whatevs Group Title

yes
