Answer :
To solve the problem of adding 670,000,000 and 700,000,000 and expressing the result in scientific notation, follow these steps:
1. Add the Numbers:
- Start by adding the two numbers:
[tex]\[
670,000,000 + 700,000,000 = 1,370,000,000
\][/tex]
2. Convert to Scientific Notation:
- Scientific notation expresses numbers as a product of a number between 1 and 10 and a power of 10.
- To express 1,370,000,000 in scientific notation, determine how many places you move the decimal point to get a number between 1 and 10. For 1,370,000,000, you move the decimal 9 places to the left.
- This gives you 1.37, and since you moved the decimal point 9 places, it becomes [tex]\(1.37 \times 10^9\)[/tex].
Given these steps, the correct answer is [tex]\(1.37 \times 10^9\)[/tex], which corresponds to option B.
