What is the result of adding 2.5x103 and 3.5x102?

Answer 1

To add (2.5 \times 10^3) and (3.5 \times 10^2), we first convert (3.5 \times 10^2) to the same power of ten as (2.5 \times 10^3). This gives us (3.5 \times 10^2 = 0.35 \times 10^3). Now, we can add the two: (2.5 \times 10^3 + 0.35 \times 10^3 = (2.5 + 0.35) \times 10^3 = 2.85 \times 10^3). Thus, the result is (2.85 \times 10^3).
