Question

If log2=0.3010 , log 3= 0.4771 , log 5=0.6990 , then find the value of log 30 .

Answer 1

First, we formulate the following expression based on the logarithm of a product

`\log (2\cdot3\cdot5)=\log 2+\log 3+\log 5`

Then, we use the given logarithms

`\log (30)=0.3010+0.4771+0.6990=1.4771`

Hence, log30 is equivalent to 1.4771.
