To find the total storage after buying the additional bytes, we need to add the current storage of the phone (1.28×10¹¹ bytes) to the additional storage (384,000,000,000 bytes).
First, let's express the additional storage in scientific notation:
384,000,000,000 = 3.84 × 10¹¹ bytes
Now, we add the two amounts together:
1.28 × 10¹¹ + 3.84 × 10¹¹
Combining these, we get:
(1.28 + 3.84) × 10¹¹ = 5.12 × 10¹¹ bytes
Thus, if you buy the additional bytes, your phone would have 5.12 × 10¹¹ bytes of storage.
So the correct response is:
5.12×10¹¹
