Answer 1

The student's cell phone has run out of memory after using 9.1 x 10^10 bytes for photos.

Step-by-step explanation:

Answer:

The student's cell phone has 6.4 x 107 bytes of memory. If 9.1 x 1010 bytes have been used for photos, we can subtract the used memory from the total memory to find out how much is left.

Using scientific notation, the calculation would be:

6.4 x 107 - 9.1 x 1010 = (6.4 - 9.1) x 107 = -2.7 x 107

So, there is -2.7 x 107 bytes of memory left, which indicates that the phone has run out of memory and the user needs to free up some space.
