Use following sequence following exactly your problem

2.998
X
(
18
/
5.874
)
2nd, 10 to power x
X
8
10 to power x
=

When evaluating a "10 to the power x" expression, you first enter the exponent number, then press the "2nd, 10 to the power" key. Same as getting the value of "sin 60", first enter 60, then the "SIN" key.

The (18/5.874) sequence in the middle has to be in (.....) is because you first have to get the value of that expression (however complicated it is) before you tell the calculator you want to raise 10 to the power of the resultant number.

How to use exponents on a scientific calculator


To enter powers of 10 exponents you have a key marked EE, or EEE, or [*10^x). When used, no 10 should appear on the command line
6.02*10^23 will be typed as 6.02EE23.
To enter powers of any base, you have the general power key. It may be marked [^], [ X^y] or [Y^x].

Calculating chemistry 1 scientific equation divided into another?


Use the rules for exponents and you will calculate it by hand
(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3
To enter powers of 10 use the short-cut key [EE]
For example to enter 6.02*10^23 type in 6.02* [EE] 23. When you use the EE key, the base (10) should not appear.

Casio FX-115ES Scientific Calculator


I have done the calculation using the the shortcut key [x10^X] to enter the exponent,and I got the correct result.
I also did the calculation by explicitly typing the 10^10 factor and I obtained the correct result.
The syntax error may come from your using the minus - sign for subtraction rather that the change sign key (-)

What is E and how do i get rid of it?


E represents the number in exponential form - which is powers of 10. For example, 5 times 8 is 40, or 40 times 10 to the power of 0 (which is one)
so 5x8=40x1. It could also be written as 4E1, or 4x10^1, which is 40.
This will most likely be the mode your calculator is in, try setting it to something like "math" mode.

When I do 10^3 it gives me 10000 and when I do 10^-2 it gives me .1 what is wrong? Do I have to preset my calculator up correctly?


It should be 0.01 not 0.1 coz its the inverse.I f you rewrite it, it would be like this 1/10 to the power of 2. When the power is negative it would be dividing one.

hope I help

Fractional powers


use the "carrot" button, ^. Type in 4^.5 and you get 2. If you are going to use fractions, use the division bar and parenthesis and not the fraction key. Example 4^(1/2) = 2
