A mobile phone holds 1.28×10^11 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)

Answer 1

To find the total storage after buying the additional bytes, you would add the two amounts of storage together:

1. Current storage: \(1.28 \times 10^{11}\) bytes
2. Additional storage: \(384,000,000,000\) bytes

First, convert \(384,000,000,000\) bytes into scientific notation:

\[ 384,000,000,000 = 3.84 \times 10^{11} \]

Now add the two amounts:

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

Thus, the total storage of the phone after purchasing the additional bytes is:

\[ \boxed{5.12 \times 10^{11}} \]
