to change the coefficient on the term that the exponent was changed.

Step 3:
Divide
the coefficients.

Step 4:
Keep the same
exponents to simplify.

Answer 1

Step 1: Add 2 to the exponent 5 to get the exponents the same for adding in scientific notation.

Step 2: Change 3.71 to 0.0371 to change the coefficient on the term whose exponent was changed (3.71×10^5 = 0.0371×10^7).

Step 3: Add the coefficients (0.0371 + 4.65 = 4.6871).

Step 4: Keep the same exponent to simplify: 4.6871×10^7.
