You can put this solution on YOUR website!
The trick is to express +2+ as a log to the base +4+
+2+=+log%28+4%2C16+%29+
+log%28+4%2Cn+%2B+3+%29+=+log%28+4%2C16+%29+
+n+%2B+3+=+16+
+n+=+13+
-----------
check answer:
+log%28+4%2Cn+%2B+3+%29+=+2+
+log%28+4%2C13+%2B+3+%29+=+2+
+log%28+4%2C16+%29+=+2+
I can rewrite this as:
+4%5E2+=+16+
+16+=+16+
OK
