What is the sum of 6.3×103 and 2.41×104? Use scientific notation to express your answer.(1 point)
3.04×10^4
To find the sum of the two numbers in scientific notation, we must first make sure that the exponents are the same.
6.3×10^3 and 2.41×10^4 cannot be added directly because the exponents are different.
To make the exponents the same, we will convert 6.3×10^3 to scientific notation with an exponent of 4.
6.3×10^3 = 0.063×10^4
Now that the exponents are the same, we can add the two numbers:
0.063×10^4 + 2.41×10^4 = 2.473×10^4
Therefore, the sum of 6.3×10^3 and 2.41×10^4 is 2.473×10^4.
To add numbers in scientific notation, you first need to make sure the exponents are the same. In this case, we can rewrite 6.3 × 10^3 as 6.3 × 10^4 (by moving the decimal point one place to the right) to match the exponent of 2.41 × 10^4.
Now, we can add the coefficients: 6.3 + 2.41 = 8.71.
Therefore, the sum in scientific notation is 8.71 × 10^4.
To find the sum of numbers expressed in scientific notation, you need to match their exponents.
Step 1: Convert 6.3 × 10^3 and 2.41 × 10^4 to the same exponent.
Since both exponents are already positive, we can convert 6.3 × 10^3 to 0.063 × 10^5.
Step 2: Add the numbers.
0.063 × 10^5 + 2.41 × 10^4 = 0.063 × 10^5 + 0.241 × 10^5
Step 3: Combine the coefficients.
0.063 + 0.241 = 0.304
Step 4: Keep the common exponent.
0.304 × 10^5
Therefore, the sum of 6.3 × 10^3 and 2.41 × 10^4 is 0.304 × 10^5.
