Use the EE or EXP key on that calculator. You will have one or the other, but not both. This key has been designed to enter numbers in scientific notation. If you are using the 10x key, then you should stop because that key was not designed for scientific notation. **To enter 3.0 x 108, all you have to type in is ** ...
A figure within a number is significant if it is there to indicate precision. If, instead, it is there just to indicate the size of the number, it is not significant. Thus, a zero to the right of the decimal at the end must always be significant, because that zero does nothing to indicate the size of the number. The nu...
**The Hydrolysis of Sucrose** Author Name **Abstract:** “Carbohydrates are one of the principal sources of food energy” (Wile, Exploring Creation, 146). Even though carbohydrates are one of the most important chemicals in the human body, they are too large a molecule to be utilized in their “raw” form. Thus, the ...
Here is the pattern we try to follow on all of our solutions. If all of the math operations are the same, i.e. all multiplication/division or all addition/subtraction, then we will not round until the very end of the calculations. If the math operations switch, i.e. switches from multiplication to addition, then we wil...
Our advanced courses (Advanced Biology, Advanced Chemistry, and Advanced Physics) cannot be used in place of our other science courses (Biology, Chemistry, or Physics). Advanced Biology has a prerequisite of Biology and Chemistry, Advanced Chemistry has a prerequisite of Chemistry, and Advanced Physics has a prerequisi...
