I assume that the question is actually 2+500+000+%2A+.00003+%2F+%28.05+%2A+5000000%29

2+500+000+=+2.5+%2A+10%5E6
0.00003+=+3.0+%2A10%5E-5
0.05+=+5.0+%2A10%5E-2
5000000=+5.0+%2A+10%5E6

The top section 2.5+%2A+10%5E6+%2A+3.0+%2A10%5E-5 simplifies to 7.5+%2A+10%5E1
The bottom section %285.0+%2A10%5E-2+%2A+5.0+%2A+10%5E6%29 simplifies to 2.5+%2A+10%5E5
The problem is now 7.5+%2A+10%5E1%2F%282.5+%2A+10%5E5%29 which is 3+%2A+10%5E-4 or .0003
