Scientific Notation and Operations

The video tutorial covers operations in scientific notation, focusing on addition, subtraction, multiplication, and division. It provides three examples: calculating the difference in mass between Earth and the Moon, determining the total length of a bridge made of segments, and comparing the speed of a cheetah to a garden snail. Each example demonstrates how to use a calculator to solve problems in scientific notation.

What are the four basic operations used in scientific notation?

• Addition, Subtraction, Multiplication, Division

• Addition, Multiplication, Division, Square Root

• Addition, Subtraction, Multiplication, Exponentiation

• Addition, Subtraction, Division, Modulus

When comparing two numbers in scientific notation, which operation is used if the phrase 'how much greater' is mentioned?

• Multiplication

• Subtraction

• Addition

• Division

What is the mass of the Earth in scientific notation?

• 5.97 times 10 to the 24th kilograms

• 7.35 times 10 to the 22nd kilograms

• 7.0 times 10 to the 1st kilograms

• 5.8965 times 10 to the 24th kilograms

How do you calculate the total length of a bridge made up of segments in scientific notation?

• By multiplying the number of segments by the length of one segment

• By dividing the total length by the number of segments

• By adding the length of each segment

• By subtracting the length of each segment

What is the total length of the bridge in scientific notation?

• 4.8 times 10 squared feet

• 1.296 times 10 to the 4th power

• 12,960 feet

• 27 times 4.8 times 10 squared feet

When comparing speeds in scientific notation, which operation is used if the phrase 'how many times greater' is mentioned?

• Addition

• Division

• Subtraction

• Multiplication

What is the speed of a cheetah in scientific notation?

• 3.0 times 10 to the negative second power

• 5.8965 times 10 to the 24th power

• 1.296 times 10 to the 4th power

• 7.0 times 10 to the first power

What is the speed of a garden snail in scientific notation?

• 7.0 times 10 to the first power

• 3.0 times 10 to the negative second power

• 1.296 times 10 to the 4th power

• 5.8965 times 10 to the 24th power

How many times greater is the speed of a cheetah compared to a garden snail?

• 2.3 times 10 to the 3rd power

• 3.0 times 10 to the negative 2nd power

• 7.0 times 10 to the 1st power

• 2.3 repeating times 10 to the 3rd power

What is the result of dividing 7.0 times 10 to the first power by 3.0 times 10 to the negative second power?

• 2.3 repeating times 10 to the 3rd power

• 1.296 times 10 to the 4th power

• 2.3 times 10 to the 3rd power

• 5.8965 times 10 to the 24th power
