On most calculators there is a key labeled "EXP" that stands for EXPONENT. The key is usually programed to mean "X 10 to the EXPONENT of" and then you press the negative key " - " and then press the number " 4 " key. So, in your problem it would be;

2.513 then press "EXP" then press " - " then press " 4 ".

You can also do it this way;

Anytime you see the base 10 to a negative exponent, you must have enough zero's + 1 to equal the exponent, like this;

10^-4 means .0001

a decimal followed by three zero's and ALWAYS ending with a one.

10^-6 means - - - .000001 - - - decimal then five zero's and a one.

The users manual for the calculator would be the best place to look for this information.
