Question

Use the given rounded values, the properties of logsand your knowledge of logarithmic functions to find thevalue of each log expression. Show your work.

Answer 1

We want to find the value for

`\log _425`

To do that, first let's rewrite this expression as

`\log _425=\log _45^2`

Using the following property

`\log _ab^c=c\log _ab`

We can rewrite our expression as

`\log _45^2=2\log _45`

Using the given value on the text, we get our answer

`\log _425=2\log _45=2\cdot1.2=2.4`
