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 ??

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??
