Use a calculator to evaluate each expression.

Round your answer to three decimal places.

log321

Short Answer

Expert verified

The value of log321is 2.771

Step by step solution

01

Step 1. Given Information

Given Expressionlog321

We have to evaluate expression by using a calculator.

02

Step 2. Solution

For easier calculation on the calculator the base should be b = e

( i.e. we should have the natural logarithm )

Therefore, we will use the change of base formula:

logaM=logbMlogba

In our case logaM=logeMlogra=lnMIna---(1)

So we havelog321=ln21ln3=2.771
