what is the sum of 6.3*10^3 and 2.41*10^4 use scientific notation to express your answer

Answer 1

To find the sum of these numbers, we need to convert them to the same power of 10:

6.3 * 10^3 = 0.63 * 10^4 (dividing by 10, we increase the exponent by 1)
2.41 * 10^4 (already in the desired format)

Now, we can add the two numbers:

0.63 * 10^4 + 2.41 * 10^4 = (0.63 + 2.41) * 10^4 = 3.04 * 10^4

So, the sum is 3.04 * 10^4.
