Question
Solve the following problem:
Perform the following operation:
3.971 × 107 + 1.98 × 104
Solution
To perform an addition/subtraction operation, first, the numbers are written in such a way that they have the same exponent. The coefficients are then added/subtracted.
3.971 × 107 + 1.98 × 104
= 3.971 × 107 + 0.00198 × 107
= (3.971 + 0.00198) × 107
= 3.97298 × 107
