To determine x, we'll apply the product and quotient rule
of logarithms:
log(b*c) = logb +
logc
loga 7+loga 3 = loga(7*3) = loga
21
The expression will
become:
loga x= loga 21 - loga
11
log(b/c) = logb -
logc
loga 21 - loga 11 =
loga(21/11)
The expression will
become:
loga x =
loga(21/11)
Since the bases are matching, we'll apply the
one to one rule:
x =
21/11
