## anonymous one year ago Okay, so I've got another log question, except the log bases are different. That difference is making me pretty confused. 2log4(9) - log2(3)

$$2log_4(9) - log_2(3)$$ yep?

4. anonymous

Yep :)

5. IrishBoy123

so you are now base switching?

6. anonymous

I believe so...

7. anonymous

(I'm finally on a computer so I can actually use proper equations yay)

8. IrishBoy123

$$\huge \log_b a = {\log_d a \over \log_d b}$$

9. IrishBoy123

so you have options here

10. anonymous

so what would be the common base? log 2?

11. IrishBoy123

dunno for sure, haven't done this in ages, but 2 sounds like a good way to start

12. IrishBoy123

you get a simple answer with bas 2 am pretty sure that @CGGURUMANJUNATH 's drawings are really helpful too but that scrawl does my head in

14. IrishBoy123

yep

15. IrishBoy123

@CGGURUMANJUNATH is doing some really cool stuff with squaring the base itself. that is definitely worth checking out

16. anonymous

Yeah :D

hanks for helping me out everyone :D
