No common factors probably making best for using logarithms.

log%28%28%284%5E10%29%2F45%29%29

log%28%284%5E10%29%29-log%28%2845%29%29

10%2Alog%28%284%29%29-log%28%284.5%2A10%29%29

Use base-Ten.

10%2Alog%28%284%29%29-log%28%284.5%29%29%2B1

10%2A%280.60206%29-0.653213%2B1

6.0206%2B1-0.653213

7.0206-0.653213

6.367387--------------------NOW, what is antilog of this?

Using software calculator instead of table of logarithms:
10%5E%286.367387%29, and using the 10^x key or button,
2330166.7, but this is too many significant figures based on the accuracy I used, so...
2330170
better expressed as highlight%282.33017%2A10%5E6%29.

Just use your calculator. It didn't ask for the EXACT value, so an approximation can be given. This is: 23,301.69. Are you sure it's not: %284%5E8+%2A+4%5E2%29%2F4%5E5?
