To find out how much storage your phone would have if you buy the additional bytes, you simply add the original storage to the additional storage.
- Original storage: \( 1.28 \times 10^{11} \) bytes
- Additional storage: \( 384,000,000,000 \) bytes, which can be expressed in scientific notation as \( 3.84 \times 10^{11} \) bytes.
Now, let's perform the addition:
\[ 1.28 \times 10^{11} + 3.84 \times 10^{11} \]
To add these, we can combine the coefficients while keeping the power of ten the same:
\[ (1.28 + 3.84) \times 10^{11} = 5.12 \times 10^{11} \]
Therefore, if you buy the additional bytes, your phone would have \( 5.12 \times 10^{11} \) bytes of storage.
The correct answer is: 5.12×10^11
