Given enough nutrients, bateria cells will multiply exponentially. Each time they dvide the number of cells will double(one cycle). So if we started with 2 cells, in the next cycle there would be 4, then 8 and so on.
If we start out with 2 cells, how many cycles would it take the bacteria to overtake the human population( 6900000000). Write the formula

Question

Given enough nutrients, bateria cells will multiply exponentially. Each time they dvide the number of cells will double(one cycle). So if we started with 2 cells, in the next cycle there would be 4, then 8 and so on. 
 If we start out with 2 cells, how many cycles would it take the bacteria to overtake the human population( 6900000000). Write the formula

kropot72 · Answer

The equation needed to solve this is
$$2^{x}=6.9\times10^{9}$$
where x is the number of cycles.
Now you need to solve the equation to find x.
