To add numbers expressed in scientific notation, we first need to align the exponents.
6.3 x 10^3 and 2.41 x 10^4 can be shifted to have the same exponent:
6.3 x 10^3 = 0.63 x 10^4 (move the decimal point in 6.3 one place to the left)
2.41 x 10^4 (no change)
Now we can add:
0.63 x 10^4 + 2.41 x 10^4 = (0.63 + 2.41) x 10^4 = 3.04 x 10^4
The sum of 6.3 x 10^3 and 2.41 x 10^4 is 3.04 x 10^4.
What is the sum of 6.3x10^3 and 2.41x10^4? Use scientific notation to express your answer.
