C 3.8 × 10^3
D 3.8 x 10^4

Answer 1

To solve \((3 × 10^4) + (8 × 10^3)\), we need to express both terms using the same power of ten.

First, we can rewrite \(8 × 10^3\) in terms of \(10^4\):

\[ 8 × 10^3 = 0.8 × 10^4 \]

Now we can add the two expressions:

\[ (3 × 10^4) + (0.8 × 10^4) = (3 + 0.8) × 10^4 = 3.8 × 10^4 \]

Thus, the answer is:

D \(3.8 × 10^4\)
