  Evaluate Log60 – Log0.3 + Log500.

Solution

= Log60 – Log0.03 + Log500.

= Log(60 x 500)

               0.03

= Log(30000)

             0.03

= Log(3000000)

              3

= Log 1,000,000

             

= Log₁₀1,000,000

= Log₁₀10⁶

            

= 6Log₁₀10

= 6 x 1

= 6

∴ Log600 – Log0.03 + Log50 = 6
