Which expression is equivalent to 415,000,000 + 558,000,000?

Question

A 9 . 73 × 10 − 7 B 9.73 × 10 6 C 9.73 × 10 7 D 9.73 × 10 8 E 9.73 × 10 9

Answer 1

To simplify the expression \(415,000,000 + 558,000,000\), we start by performing the addition:

\[ 415,000,000 + 558,000,000 = 973,000,000 \]

Next, we will express \(973,000,000\) in scientific notation. We can rewrite \(973,000,000\) as:

\[ 973,000,000 = 9.73 \times 10^8 \]

Thus, the equivalent expression to \(415,000,000 + 558,000,000\) in scientific notation is:

\[ \boxed{9.73 \times 10^8} \]

This indeed corresponds to option D \(9.73 \times 10^8\).
