Add. Write your answer in scientific notation.
(4.13 × 10^5) + (6.7 × 10^5)
1. 1.083 × 10^7
2. 1.083 × 10^6
3. 1.083 × 10^8
4. 1.083 × 10^9
To add the numbers in scientific notation, you should ensure that the exponents are the same, which they are in this case (both are (10^5)).
1. Add the coefficients:
(4.13 + 6.7 = 10.83)
2. The sum can be written as:
(10.83 × 10^5)
3. Now, we must express this in proper scientific notation. Scientific notation requires the coefficient to be between 1 and 10. So, we adjust it:
(10.83 = 1.083 × 10^1)
4. Therefore:
(10.83 × 10^5 = 1.083 × 10^{5+1} = 1.083 × 10^6)
So the answer is 2. 1.083 × 10^6.
