Chapter 10: Q. 400 (page 1064)

In the following exercises, find the exact value of each logarithm without using a calculator.
$\log_{2} (32)$

Short Answer

Expert verified

The value is $5$ .

Step by step solution

Step 1. Form a logarithmic equation and write its equivalent exponential form

Consider the expression $\log_{2} (32)$ .

Setting the expression equal to $x$ we get,

$\log_{2} (32) = x$

And its equivalent exponential form is given as $2^{x} = 32$ .

Step 2. Compare the exponents

The number $32$ can be equivalently written as $2^{5}$ . So we get

$2^{x} = 32 2^{x} = 2^{5}$

Now, as the base is the same, so on comparing the exponents we get

$x = 5$

Thus the value of $\log_{2} (32)$ is $5$ .
