Final answer:
The number of cells in the culture on day 8 will be 4,096.
Step-by-step explanation:
The number of cells in the culture is growing exponentially, and can be expressed as 2n, where n is the number of generations. Given that the number of cells on day 0 is 1,000 and on day 4 is 64,000, we can calculate the value of n. By solving the equation 2n = 64,000, we find that n = 6. So, the number of cells on day 8 can be calculated as 26 = 64 * 64, which is equal to 4,096 cells.
