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.

Answer 1

To find the total storage after buying the additional bytes, you need to add the original storage capacity to the additional bytes purchased.

Original storage capacity: 1.28 × 10^11 bytes
Additional bytes purchased: 384,000,000,000 bytes

Total storage = Original storage capacity + Additional bytes purchased
= 1.28 × 10^11 bytes + 384,000,000,000 bytes

To add these numbers together, first rewrite 384,000,000,000 in scientific notation:
384,000,000,000 = 3.84 × 10^11

Now, add the numbers:
1.28 × 10^11 bytes + 3.84 × 10^11 bytes = (1.28 + 3.84) × 10^11 bytes = 5.12 × 10^11 bytes

Therefore, your phone would have a storage capacity of 5.12 × 10^11 bytes if you buy the additional bytes.
