Question

Find (7 × 10^5
) + (2 × 10^3
).

Answer 1

To solve \( (7 \times 10^5) + (2 \times 10^3) \), we first need to express both terms with the same power of ten to make the addition straightforward.

We can rewrite \( 2 \times 10^3 \) in terms of \( 10^5 \) by converting it:

\[
2 \times 10^3 = 2 \times 10^3 \times \frac{10^2}{10^2} = 2 \times 100 \times \frac{1}{100} = 200 \times 10^1 = 0.02 \times 10^5
\]

Thus, we find:

\[
2 \times 10^3 = 0.02 \times 10^5
\]

Now we can add the two terms together:

\[
(7 \times 10^5) + (0.02 \times 10^5) = (7 + 0.02) \times 10^5 = 7.02 \times 10^5
\]

Thus, the final answer is:

\[
\boxed{7.02 \times 10^5}
\]
