LOGARITHMS 8

Evaluate Log60 – Log0.3 + Log50.

Solution

= Log60 – Log0.3 + Log50.

= Log(60 x 50)

              0.3

= Log(3000)

           0.3

= Log(30,000)

              3

= Log 10,000

              

= Log₁₀10,000

= Log₁₀10⁴

            

= 4Log₁₀10

= 4 x 1

= 4

∴ Log60 – Log0.3 + Log50 = 4
