Equation: 2log(base)2 (a) - 3 - log(base)10 (25)
I'm on the right track, but I'm having trouble about what to do with the '-3'
The answer is log(base)10 (a^2/25000)
but I got log(base)10 (a^2/25) - 3

... 2. log₁₀ a - 3 - log₁₀ 25
= log₁₀ (a²) - [ 3( 1 ) + log₁₀ 25 ]
= log₁₀ (a²) - [ 3 ( log₁₀ 10 ) + log₁₀ 25 ]
= log₁₀ (a²) - [ ( log₁₀ (10)³) + log₁₀ 25 ]
= log₁₀ (a²) - log₁₀ ((1000)(25))
= log₁₀ ( a² / 25000 ) ........................................ Ans.
