-------------
base 10 is the default, you don't need to mention it.
1/2log(25)- 2log(3) + log(18)
= log(5) - log(9) + log(18)
= log(5*18/9) = log(10)
= 1

1/2logbase10 25-2logbase10 3+logbase10 18
Move the integers (1/2 and 2) to front and make them powers
logbase10 25^1/2 - logbase10 3^2 + logbase10 18
25^1/2 = square root of 25
logbase10 5 - logbase10 9 + logbase10 18
logbase10 5 * 18/9
logbase10 10 = 1
Hope this helps.
