LOG 1

Evaluate Log60 – Log0.3 + Log5000.

Solution

= Log60 – Log0.3 + Log5000.

= Log(60 x 5000)

               0.3

= Log(300000)

             0.3

= Log(3,000,000)

              3

= Log 1,000,000

             

= Log₁₀1,000,000

= Log₁₀10⁶

            

= 6Log₁₀10

= 6 x 1

= 6

∴ Log60 – Log0.3 + Log5000 = 4
