Evaluate Log60 – Log0.3 + Log500.

Solution

= Log60 – Log0.3 + Log500.

= Log(60 x 500)

               0.3

= Log(30000)

             0.3

= Log(300,000)

              3

= Log 100,000

             

= Log₁₀100,000

= Log₁₀10⁵

            

= 5Log₁₀10

= 5 x 1

= 5

∴ Log600 – Log0.3 + Log50 = 4
