mathematically Evaluate without using tables 2 log base 10 raised 2 power 5 + log base 10 36 - log base10 9 that is, 2log10 5 +log 10 36 - log 10 9

Answer 1

The words are confusing, but it appears that you have

2log5 + log36 - log9
= log(25*36/9)
= log100
= 2
Rather than trying to toss in all those a0's, just say at the start that all logs are base 10.

Answer 2

True Steve. I searched. It's confusing to me too.
