Question

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 385,280,000,000 385,280,000,000 512×109 512 times 10 superscript 9 baseline 5.12×1011

Answer 1

To find the total storage after purchasing the additional bytes, we need to add the initial storage and the additional storage.

Initial storage:
1.28 × 10^11 bytes

Additional storage:
384,000,000,000 bytes = 3.84 × 10^11 bytes

Now, we can add these two numbers together:

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

Therefore, the total storage of your phone would be:

\[ 5.12 × 10^{11} \text{ bytes} \]

So, the correct answer is:

5.12×10^11
