Find the number of digits in 19 to the 28th power

Let's actually ask for it.

Let's calculate the common logarithm of 19 to the 28th power.

\begin{eqnarray}
\log_{10}19^{28}&=&28 \log_{10}19\\
&=&28\times 1.2787\cdots\\
&=&35.805
\end{eqnarray}

In other words,
We can say that $19^{28}=10^{35.805}$, so we know that $19^{28}$ has 36 digits.

How to find the number of digits

To find the number of digits in $19^{28}$, 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.
