A mobile phone holds 1.28x10^11 bytes of storage. You can also pay more money to get an additional 384,000,000,000 bytes. The answer should be in scientific form.
Total storage on the mobile phone after paying for additional storage:
1.28x10^11 bytes + (384,000,000,000 bytes) = 3.84x10^11 bytes
Thus, the total storage on the mobile phone in scientific notation is 3.84x10^11 bytes.
