[jamjam]

In expressing as an equivalent expression that is a sum of logarithmic is my answer correct?
logunderscoret(3ab)
=logunderscoret3,logunderscoreta,logunderscoretb
=0.683 + 1 = 1.683

logunderscoret(3ab) = logunderscoret(3) + logunderscoret(a) + logunderscoret(b)

If you do not know the values of t, a, or b, you cannot evaluate further.
