Given that log2=0.3010, log7=0.845 and log5=0.699
Evaluate log45
~~~~~~~~~~~~~~~~~~~~~

45 = 9*5 = 3*3*5.

THEREFORE,   log(45) = log(3*3*5) = log(3) + log(3) + log(5) = 2*log(3) + log(5).

In this problem, given log(7) = 0.845 is IRRELEVANT.

Log(3) should be given in order for the solution be possible, but it is NOT GIVEN,   and,   therefore,
the solution CAN NOT be obtained.

As posed, given problem is a   F A K E.
