Scientific Notation Operations

The video tutorial explains how to divide numbers in scientific notation. It outlines the steps: divide the coefficients, keep the base of 10, and subtract the exponents. The final result must be in proper scientific notation, meaning the coefficient should be between 1 and 9. Two examples are provided: one where the result is already in the correct form, and another where the coefficient needs adjustment by moving the decimal point, which affects the exponent.

What is the first step when dividing numbers in scientific notation?

• Divide the coefficients

• Subtract the exponents

• Add the exponents

• Multiply the coefficients

What must be done to ensure the result is in proper scientific notation?

• The coefficient must be less than 1

• The coefficient must be between 1 and 9

• The coefficient must be greater than 9

• The exponent must be zero

In the first example, what is the result of dividing the coefficients 8 and 2?

• 6

• 4

• 8

• 2

In the first example, what is the result of subtracting the exponents 8 and 5?

• 4

• 5

• 3

• 2

In the second example, what is the initial result of dividing 4.25 by 5?

• 3.5

• 2.5

• 1.25

• 0.85

How is the coefficient adjusted in the second example to ensure it is between 1 and 9?

• Subtract 1 from the coefficient

• Add 1 to the coefficient

• Move the decimal to the right

• Move the decimal to the left

What happens to the exponent when the decimal is moved to the right in the second example?

• The exponent becomes zero

• The exponent remains the same

• The exponent decreases

• The exponent increases
