The video tutorial explains how to convert a number into scientific notation. It begins with an introduction to the problem of converting 71 * 10^-1 into scientific notation. The instructor explains the format of scientific notation, where a number is expressed as A * 10^F, with A between 1 and 10. The tutorial then demonstrates the conversion process, moving the decimal point to achieve the correct format. The instructor provides a detailed explanation of the steps involved, including adjusting the exponent to maintain the value of the number. The video concludes with the final conversion and a summary of the process.

What is the requirement for the coefficient in scientific notation?

• It must be a negative number.

• It must be a whole number.

• It must be between 1 and 10.

• It must be greater than 10.

What happens to the decimal point when converting 71 to 7.1 in scientific notation?

• It disappears.

• It moves to the left.

• It stays in the same place.

• It moves to the right.

Why is it unnecessary to move the decimal point further after converting 71 to 7.1?

• Because the exponent is negative.

• Because 7.1 is already between 1 and 10.

• Because the number is already whole.

• Because the decimal point cannot move left.

How does the exponent change when converting 71 * 10 to the negative first to scientific notation?

• It doubles.

• It becomes negative.

• It becomes zero.

• It becomes positive.

What is the final scientific notation of 71 * 10 to the negative first?

• 71 * 10^0

• 7.1 * 10^0

• 71 * 10^1

• 7.1 * 10^1
