Question

Fill in the blanks with the correct steps for solving: (3.71 × 10^5) + (4.65 x 10^7)
(5 points)
Step 1: _______ to get the exponents the same for adding in Scientific Notation. (Answer Choices: add 2 to the exponent 5, subtract 2 from the exponent 5, add the exponents together, subtract the exponents)

Step 2: _______ to change the coefficient on the term that the exponent was changed.

Step 3: _______ the coefficients.

Step 4: _______ the exponents to simplify.

Step 5: _______ is the final answer in Scientific Notation.

Answer 1

On step two what do you change?

Answer 2

So would you ,
Change 3.71 to 371
Change 4.65 to 0.045
Change 4.65 to 0.0465
Change 3.71 to 0.0371

Answer 3

Step 1: Add the exponents together to get the exponents the same for adding in Scientific Notation.

Step 2: Multiply the coefficient on the term that the exponent was changed.

Step 3: Add the coefficients.

Step 4: Keep the exponent the same to simplify.

Step 5: 4.65 x 10^7 is the final answer in Scientific Notation.

Answer 4

On step two, you multiply the coefficient on the term that the exponent was changed.

Answer 5

You would change 4.65 to 0.0465.
