+7.2%5E3+=+3%2Ax%5E%28-1%29+
+log%28+7.2%5E3+%29+=+log%283%29+%2B+log%28+x%5E%28-1%29+%29+
+3%2Alog%28+7.2+%29+=+log%283%29+-+log%28x%29+
+log%28x%29+=+log%283%29+-3%2Alog%287.2%29+
-------------------------------------
check answer:
+log%28x%29+=+.477121+-+3%2A.85733+
+log%28x%29+=+.477121+-2.71997+
+log%28x%29+=+-2.09488+
+x+=+.0080375+
and
+373.248+=+3%2Fx+
+373.248+=+3%2F.0080375+
+373.248+=+373.250+
error due to rounding off I think
