The <em><u>correct answer</u></em> is:
7.8 × 10⁷
Explanation:
To write a number in scientific notation, we want the decimal behind the first non-zero digit in the number. The first non-zero digit in 78 is 7; this means we want 7.8. In order to have the decimal point behind the 7, we need to move the decimal 7 places. This is the exponent of 10 in our scientific notation, which gives us
7.8 × 10⁷
Expression 1 is the main equation and expression 2 is the more simplified equation from expression 1.
326 + 37g
-287 - 23g
-----------------
38 + 14g
(Though I think 38 is suppose to be 39.)
