LOGARITHMS K12

 Evaluate Log60 – Log0.003 + Log500.

 

Solution

 

= Log60 – Log0.003 + Log500.

 

= Log(60 x 500)

              0.003

 

= Log(30000)

            0.003

 

= Log(30,000,000)

                 3

 

= Log 10,000,000

             

= Log₁₀10,000,000

 

= Log₁₀10⁷

            

= 7Log₁₀10

 

= 7 x 1

 

= 7

 

∴ Log600 – Log0.003 + Log50 = 7
