7. gohangoku58

i am writing this for third time. \(\huge \log a^b=b\log a\)

8. iheartfood

no.. lol

9. iheartfood

okay so i get log(5)/log(0.693) ??? idk really... :/

10. gohangoku58

\(\huge \log 32=\log 2^5=5\log 2=?\)

11. iheartfood

umm 1.505149978 ??

12. jim_thompson5910

ln(32) = ln(2^5) ln(32) = 5*ln(2) ln(32) = 5*[Given value for ln(2)] ln(32) = ???

13. iheartfood

3.465735903 ??? so my answer is C. 3.466 ??

14. jim_thompson5910

yep

15. gohangoku58

sorry, lost connection...

16. iheartfood

okay thanks!! wait so ln is different that log right?? cuz i think i entered log and thats how i got 1.505... btu ln i got 3.466..... :/ whats the difference??

17. gohangoku58

log has base = 10 ln has base = e = 2.8 approx...

18. iheartfood
