make use of your main "log rules"
log (8/3) = log 8 - log 3 = 2.079 - 1.099
= 0.98
log 24 = log (3x8) = log 3 + log 8
= ....
log 25 = log 5^2
= 2 log 5
= ...
If loga 8=2.079, loga 5=1.609, and loga 3=1.099, find the following?
19.) loga 8/3 is this 1.89?
20.) loga 24 Not sure
21.) loga 25 not sure how to do this

Okay I got it
log (8/3) = log 8 - log 3 = 2.079 - 1.099
= 0.98
log 24 = log (3x8) = log 3 + log 8
= 3.688
log 25 = log 5^2
= 2 log 5
= 2.138
log (8/3) = log 8 - log 3 = 2.079 - 1.099
= 0.98
log 24 = log (3x8) = log 3 + log 8
= 3.688
log 25 = log 5^2
= 2 log 5
= 2.138
great,
BTW, how would you find 'a' itself?
