1 answer

Step 1: Rewrite 3.71×10^5 as 0.000371×10^8 to make the exponents the same.

Step 2: Rewrite 0.000371×10^8 as 3.71×10^7 to change the coefficient.

Step 3: Add the coefficients: 3.71 + 4.65 = 8.36.

Step 4: Keep the exponent from the larger term: 8.36×10^7.

Therefore, (3.71×10^5) + (4.65×10^7) = 8.36×10^7.
