College Algebra question.PLEASE SHOW ALL WORK. Also can you explain how to simply on the calculator (how to enter it). I\'m using TI-30Xa. PROBLEM: Calculate the exact value of log3(25)·log5(7)·log7(27)
Solution
log3(25)·log5(7)·log 7(27)
loga(b)=lna/lnb
=(ln(25)/ln(3))(ln(7)/ln(5))(ln(27)/ln(7))
ln(25)=ln(5^2)=2ln(5)
ln(27)=ln(3^3)=3ln(3)
=(2ln(5)/ln(3))(ln(7)/ln(5))(3ln(3)/ln(7)
=6
Thank you
