Answer 1

To calculate the total storage of your mobile phone after purchasing the additional bytes, you can add the two amounts together.

1. Original storage: $1.28\times {10}^{11}$ bytes
2. Additional storage: $384,000,000,000$ bytes, which is $3.84\times {10}^{11}$ bytes in scientific notation.

Now, adding these two values:

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

So the total storage of your phone after buying the additional bytes would be $5.12\times {10}^{11}$ bytes.

Thus, the correct response is:

5.12×10¹¹
