What is the sum of 6.3 x 10^3 and 2.41 x 10^4? Use scientific notation to express your answer.(1 point)

Answer 1

To add numbers in scientific notation, the exponents must be the same. We can rewrite 6.3 x 10^3 as 0.63 x 10^4. Now we can add the two numbers:

0.63 x 10^4 + 2.41 x 10^4 = (0.63 + 2.41) x 10^4

The sum of 0.63 and 2.41 is 3.04, so the sum in scientific notation is:

3.04 x 10^4
