To find the total storage your phone would have after purchasing the additional bytes, we first need to add the two storage amounts together.
- Initial 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, we can perform the addition:
\[ 1.28 \times 10^{11} + 3.84 \times 10^{11} = (1.28 + 3.84) \times 10^{11} = 5.12 \times 10^{11} \]
Thus, if you buy the additional bytes, the total storage on your phone would be:
5.12×10^{11} bytes
