Engineering Notation Concepts

This video tutorial explains how to convert numbers into engineering notation, highlighting its differences from scientific notation. It provides examples and step-by-step instructions for converting both large numbers and numbers less than one, emphasizing the importance of exponents being multiples of three. The video concludes with advanced examples and encourages viewers to seek further help if needed.

What is a key difference between engineering notation and scientific notation?

• Scientific notation allows any number of digits to the left of the decimal.

• Engineering notation does not use exponents.

• Engineering notation uses base 2.

• The exponent in engineering notation is a multiple of three.

In engineering notation, how many digits can be to the left of the decimal point?

• One to three digits

• Two to four digits

• Only one digit

• Any number of digits

Why can't 10^4 be used in engineering notation?

• It is too large of an exponent.

• It is not a power of ten.

• It requires more than three digits to the left of the decimal.

• Four is not a multiple of three.

What is the correct engineering notation for the number 21840?

• 21.84 * 10^3

• 2.184 * 10^3

• 2.184 * 10^4

• 2.84 * 10^3

How should digits be grouped when converting numbers less than one into engineering notation?

• In pairs of two

• Individually

• In groups of three

• In groups of four

What is the engineering notation for 0.736492?

• 736492 * 10^-6

• 736.492 * 10^-3

• 73.6492 * 10^-2

• 7.36492 * 10^-1

What is the final engineering notation for a large number like 472000000?

• 472 * 10^7

• 47.2 * 10^9

• 4.72 * 10^8

• 4.72 * 10^9

Why is it important to adjust the decimal point when converting to engineering notation?

• To ensure the exponent is a multiple of three

• To eliminate the decimal point

• To make the number smaller

• To increase the number of digits

What should you do if the initial scientific notation does not meet engineering notation criteria?

• Remove the exponent

• Add more digits to the left of the decimal

• Adjust the exponent to be a multiple of three

• Change the base to 2

What is a common mistake when converting to engineering notation?

• Forgetting to include an exponent

• Using base 2 instead of base 10

• Having more than three digits to the left of the decimal

• Using a non-multiple of three as the exponent
