Problem 104
Question
How do you know if a number is written in scientific notation?
Step-by-Step Solution
Verified Answer
A number is written in scientific notation if it is the product of a number greater than or equal to 1 and less than 10, and a power of 10.
1Step 1: Identify the Characteristics
Identify if the number is written as a multiplication of two parts. The first part should be a number greater than or equal to 1 and less than 10. The second part must be 10 raised to the power of a positive or negative integer.
2Step 2: Check the First Part
Check if the first part of the multiplication is a number greater than or equal to 1 and less than 10. If it is, then proceed to the next step. If not, the number is not written in scientific notation.
3Step 3: Check the Second Part
Check if the second part is 10 raised to a power. The power can be a positive, negative or zero integer. If the second part meets this condition, the number is written in scientific notation. If not, the number is not in scientific notation.
