What is the sum of 6.3×103 and 2.41×104 ? Use scientific notation to express your answer.(1 point)
6.3 × 10^3 + 2.41 × 10^4 = 6.3 × 10^3 + 24.1 × 10^3
= (6.3 + 24.1) × 10^3
= 30.4 × 10^3
= 3.04 × 10^4

To add the numbers, we need to first align the powers of 10.
6.3 × 10^3 can be rewritten as 0.0063 × 10^4.
Now, we can add the numbers:
0.0063 × 10^4 + 2.41 × 10^4 = (0.0063 + 2.41) × 10^4
= 2.4163 × 10^4.
So, the sum of 6.3×10^3 and 2.41×10^4 is 2.4163×10^4, expressed in scientific notation.
To find the sum of numbers expressed in scientific notation, you need to align the exponents and then add the coefficients.
Let's calculate the sum of 6.3×10^3 and 2.41×10^4 using scientific notation:
1. Align the exponents: In this case, the exponents are already aligned since both numbers are in scientific notation.
2. Add the coefficients: Add the coefficients of the numbers. 6.3 + 2.41 = 8.71.
3. Keep the common exponent: Since the exponents are aligned, keep the exponent from one of the numbers. In this case, both numbers have positive exponents, so we keep the positive exponent.
Therefore, the sum of 6.3×10^3 and 2.41×10^4 is 8.71×10^4.
