Operations with Scientific Notation: Addition, Subtraction, Multiplication, and Division

This video tutorial by Mr. Honker covers operations with scientific notation, including multiplication, division, addition, and subtraction. It explains how to handle the powers of 10 and provides examples for each operation. The video also discusses two methods for adding and subtracting numbers in scientific notation: converting to standard form and using a common power of 10.

What operation do you perform on the powers of ten when multiplying two numbers in scientific notation?

• None of the above

• Divide the exponents

• Subtract the exponents

• Add the exponents

If you multiply 1.6 x 10^6 by 2 x 10^3, what is the resulting power of ten?

• 10^9

• 10^8

• 10^18

• 10^3

When dividing numbers in scientific notation, what should you do with the exponents of ten?

• Add the exponents

• Subtract the exponents

• Multiply the exponents

• None of the above

What is the result of dividing 6 x 10^-5 by 8 x 10^3?

• 0.75 x 10^-8

• 7.5 x 10^-9

• 7.5 x 10^-8

• 0.75 x 10^-2

How do you adjust the decimal place when the division of numbers in scientific notation results in more than one digit before the decimal?

• Move the decimal to the left

• Add to the exponent

• Subtract from the exponent

• Move the decimal to the right

What is the first method for adding numbers in scientific notation?

• Multiply the coefficients

• Convert to standard form and add

• Use a common power of ten

• None of the above

When adding 4 x 10^3 and 2 x 10^3, what is the result using the second method?

• 2 x 10^6

• 8 x 10^3

• 6 x 10^3

• 6 x 10^6

In subtraction, if the powers of ten are different, what must you do before performing the operation?

• Subtract the smaller exponent from the larger

• Convert to a common power of ten

• None of the above

• Add the exponents

What is the result of 3.2 x 10^-4 minus 1.6 x 10^-2 in scientific notation?

• -1.584 x 10^-4

• -1.568 x 10^-2

• -1.584 x 10^-2

• -1.568 x 10^-4

How do you handle different exponents when subtracting in scientific notation?

• Adjust to a common exponent

• Add the exponents

• Multiply the exponents

• Ignore the exponents
