## Calculating 8 to the 87th Power

8 to the 87th power is simply 8 multiplied by 87 times.

Basically, the only way to find it is by multiplication.

Also, you can use google search.

For example, if you search for "14 to the 21st power" on google, a calculator will come up and tell you the answer.

As mentioned above, calculating the power is difficult, so it may be obtained as step 1.

Next, let's find the number of digits in $8^{87}$.

## Number of digits in 8 to the 87th power

Calculating $8^{87}$ gives us 79 digits. Calculating the number of digits in 8 to the 87th power

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

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.
