+log%28+5%2C+%28+z%2F25%29%5E3+%29+
+log%28+5%2C+%28+z%5E3%2F25%5E3%29+%29+
+log%28+5%2C%28+z%5E3%29+%29+-+log%28+5%2C+%2825%5E3%29+%29+
+3%2Alog%28+5%2C+%28z%29+%29+-+3%2A%28+log%28+5%2C+25+%29%29+
+3%2Alog%28+5%2C+%28z%29+%29+-+3%2A2+
+3%2Alog%28+5%2C%28z%29+%29+-+6+
-------------------
check answer
I will suppose that +z+=+125+
+log%28+5%2C+%28+z%2F25%29%5E3+%29+
+log%28+5%2C+%28+125%2F25%29%5E3+%29+
+log%28+5%2C+%285%5E3%29+%29+=+3+
and
+3%2Alog%28+5%2C%28z%29+%29+-+6+
+3%2Alog%28+5%2C%28125%29+%29+-+6+
+3%2Alog%28+5%2C+%285%5E3%29+%29+-+6+
+3%2A3+-+6+=+9+-+6+
+9+-+6+=+3+
OK
