Answer 1

To add the numbers \( 6.3 \times 10^3 \) and \( 2.41 \times 10^4 \), you first need to express them with the same power of ten.

1. Convert \( 6.3 \times 10^3 \) to the same power of ten as \( 2.41 \times 10^4 \):

   • \( 6.3 \times 10^3 = 0.63 \times 10^4 \)

2. Now we can add the two numbers:

   • \( 0.63 \times 10^4 + 2.41 \times 10^4 = (0.63 + 2.41) \times 10^4 \)
   • \( 0.63 + 2.41 = 3.04 \)

3. So, the sum is:

   • \( 3.04 \times 10^4 \)

The answer in scientific notation is \( 3.04 \times 10^4 \).
