Find the number of digits in 9 to the 26th power

Let's actually ask for it.

Let's calculate the common logarithm of 9 to the 26th power.

\begin{eqnarray}
\log_{10}9^{26}&=&26 \log_{10}9\\
&=&26\times 0.9542\cdots\\
&=&24.81
\end{eqnarray}

In other words,
We can say that $9^{26}=10^{24.81}$, so we know that $9^{26}$ has 25 digits.

How to find the number of digits

To find the number of digits in $9^{26}$, 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.
