Simplify this expression and put your answer in Scientific Notation: (3.71 x 10^5) + (4.65×10^7) (4 points)
Step 1: ___to get the exponents the same for adding in <options: do i add the exponents, subtract 2 from the exponent 5, subtract the exponent, or add 2 to the exponents 5
Step 2: ____ to change the coefficient on the term that the exponent was changed.
Step 3: ____to change the exponent for Scientific Notation
Step 4: ____is the final answer.
Step 1: Add the exponents: 5 + 7 = 12
Step 2: Keep the coefficients the same: 3.71 + 46.5 = 50.21
Step 3: Change the exponent to match the sum: 50.21 x 10^12
Step 4: The final answer is 5.021 x 10^13
