Consider the base 3 number:
0 . 11002 11002 11002 ... _3
Find a regular, base 10 fraction (numerator is a base 10 integer; denominator is, too) that has this representation
Hint: Think about converting 0. 4386 4386 4386 ... into a fraction

for today's problem, writing a:=log(s), b:=log(t), it asks:
if a+b=5 and a-b=1/2, what is a?
adding equations and dividing by two:
a = 11/4
not the toughest log problem!
