A mobile phone holds 1.28×1011 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)

385.28×1011

Answer 1

To find the total storage of the mobile phone after purchasing the additional bytes, we need to add the two amounts of storage together.

1. The initial amount of storage is:
   \( 1.28 \times 10^{11} \) bytes

2. The additional storage to be added is:
   \( 384,000,000,000 \) bytes, which can be written in scientific notation as:
   \( 3.84 \times 10^{11} \) bytes

Now, we can add these two amounts together:

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

Therefore, the total storage would be:

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