Find the number of digits in 8 to the 87th power

Let's actually ask for it.

Let's calculate the common logarithm of 8 to the 87th power.

\begin{eqnarray}
\log_{10}8^{87}&=&87 \log_{10}8\\
&=&87\times 0.903\cdots\\
&=&78.568
\end{eqnarray}

In other words,
We can say that $8^{87}=10^{78.568}$, so we know that $8^{87}$ has 79 digits.

How to find the number of digits

To find the number of digits in $8^{87}$, use common logarithms.

By using the common logarithm, we can calculate the power of 10, so we know the number of digits.

For example, $10^1=10$ is 2 digits.
On the other hand, $10^2=100$, so 3 digits.

So $10^a$ has $10+1$ digits.
If $a$ is a decimal, the number of digits is the integer part plus 1.

$a=11.34$ will be 12 digits.
