OpenStudy (anonymous):

32 = 2^(....?)

OpenStudy (anonymous):

2^5 ?

OpenStudy (anonymous):

@gohangoku58 @jim_thompson5910 ?? :O

OpenStudy (anonymous):

yes, now u know which property of log to use ?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

no.. lol

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

umm 1.505149978 ??

jimthompson5910 (jim_thompson5910):

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

OpenStudy (anonymous):

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

jimthompson5910 (jim_thompson5910):

yep

OpenStudy (anonymous):

sorry, lost connection...

OpenStudy (anonymous):

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??

OpenStudy (anonymous):

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

OpenStudy (anonymous):

so thats why sometimes they are the same, but sometimes they are diff?? but tin the end they are diff??
