<PRE><B>Question 1187264</B>
.
Given that log2=0.3010, log7=0.845 and log5=0.699
Evaluate log45
~~~~~~~~~~~~~~~~~~~~~



45 = 9*5 = 3*3*5.



THEREFORE,  &amp;nbsp;&amp;nbsp;log(45) = log(3*3*5) = log(3) + log(3) + log(5) = 2*log(3) + log(5).



In this problem,  &amp;nbsp;given &amp;nbsp;log(7) = 0.845 &amp;nbsp;is &amp;nbsp;IRRELEVANT.



Log(3) &amp;nbsp;should be given in order for the solution be possible, &amp;nbsp;but it is &amp;nbsp;NOT &amp;nbsp;GIVEN, &amp;nbsp;&amp;nbsp;and, &amp;nbsp;&amp;nbsp;therefore,

the solution &amp;nbsp;CAN &amp;nbsp;NOT &amp;nbsp;be obtained.

As posed, &amp;nbsp;given problem is &amp;nbsp;a &amp;nbsp;&amp;nbsp;F A K E.
