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)

Question

O 385.28 × 1011
• 5.12 × 1011
• 385,280,000,000
• 512 × 109

Answer 1

To find the total storage after buying the additional bytes, we start with the existing storage and then add the additional storage.

1. Existing storage: \(1.28 \times 10^{11}\) bytes
2. Additional storage: \(384,000,000,000\) bytes, which can be expressed in scientific notation as \(3.84 \times 10^{11}\) bytes.

Now, we add the two amounts together:

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

Thus, the total storage after buying the additional bytes is \(5.12 \times 10^{11}\) bytes.

The correct answer is: • 5.12 × 10^11
