A mobile phone holds 1.28×10^11

Question

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)

385,280,000,000

385.28×10^11

512×10^9

5.12×10^11

Answer 1

To find the total storage if you buy the additional bytes, you need to add the initial storage to the additional storage:

1. Initial storage: \( 1.28 \times 10^{11} \) bytes
2. Additional storage: \( 384,000,000,000 \) bytes, which can be rewritten in scientific notation as \( 3.84 \times 10^{11} \) bytes.

Now, we add them together:

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

So, the total storage after buying the additional bytes is:

\[ \text{Answer: } 5.12 \times 10^{11} \]

Thus, the correct response is:

5.12×10^11
