Hey there,My questions state

Solve algebraically without using logarithms (1/8)^2x = 16^x-5

And : a population of bacteria in a glass of milk on the counter is quadrupling every half an hour

A) write a function for growth p(t) where t is in hours

B) now t in minutes

For a I got p(.5)=A(4)^t(.5) I put .5 because it's in hours so half of one

for B I got p(30)=a(4)^t/30

please help!!
