Answer:

#e^4~~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 #-:# button.

#e ~~ 2.718281828#

Select 2ND #-:# ^ 4 ENTER

#e^4~~54.5982#

If you aren't able to use a FLOAT, you can always round #e^4 ~~ 54.59815003# to the nearest ten thousandths to get #54.5982#
