# How do you evaluate e^4 using a calculator to four decimal places?

May 28, 2017

${e}^{4} \approx 54.5982$

#### Explanation:

Given: ${e}^{4}$

It would depend on the type of calculator you are using.

TI 83, 84, 84+: Select MODE and arrow down to FLOAT. Arrow over to 4 and select ENTER.

Exit out of MODE by selecting 2ND QUIT (above the MODE).

$e$ is an irrational number similar to $\pi$. It can be found above the $\div$ button.

$e \approx 2.718281828$

Select 2ND $\div$ ^ 4 ENTER

${e}^{4} \approx 54.5982$

If you aren't able to use a FLOAT, you can always round ${e}^{4} \approx 54.59815003$ to the nearest ten thousandths to get $54.5982$
