A mobile phone holds 1.28 x 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 purchasing the additional bytes, we need to add the two storage amounts together:

1. The initial storage of the mobile phone: \[ 1.28 \times 10^{11} \text{ bytes} \]

2. The additional storage that can be purchased: \[ 384,000,000,000 \text{ bytes} = 3.84 \times 10^{11} \text{ bytes} \]

Now, we add these two values together: \[ 1.28 \times 10^{11} + 3.84 \times 10^{11} \] First, we can add them directly since they are already in the same order of magnitude: \[ (1.28 + 3.84) \times 10^{11} = 5.12 \times 10^{11} \text{ bytes} \]

Therefore, the total storage of the phone after buying the additional bytes is: \[ \boxed{5.12 \times 10^{11} \text{ bytes}} \]
