A mobile phone holds 1.28×1011
bytes of storage. You can also pay more money to get an additional 384,000,000,000 bytes. How much storage would your phone have if you buy the additional bytes? The answer should be in scientific notation.(1 point)
Responses

385.28×1011
385.28 times 10 superscript 11 baseline

5.12×1011
5.12 times 10 superscript 11 baseline

385,280,000,000
385,280,000,000

512×109

Answer 1

To find the total storage in your mobile phone after buying the additional bytes, we need to add the initial storage and the additional storage.

1. The initial storage is \( 1.28 \times 10^{11} \) bytes.
2. The additional storage is \( 384,000,000,000 \) bytes, which can be expressed in scientific notation as \( 3.84 \times 10^{11} \) bytes.

Now, we can add these two values together:

\[
1.28 \times 10^{11} + 3.84 \times 10^{11} = (1.28 + 3.84) \times 10^{11} = 5.12 \times 10^{11}
\]

Thus, the total storage would be \( \mathbf{5.12 \times 10^{11}} \) bytes.

The correct response from the options provided is:

**5.12×10^11 (5.12 times 10 superscript 11 baseline)**.
