A population of a bacteria colony doubles every 3 hours. If there are currently 500 bacteria, how many will there be after 12 hours?

The doubling period of a bacterial population is 15 minutes. At time \( t=80 \) minutes, the bacterial population was 60000 . What was the initial population at time \( t=0 \) ? Find the size of the bacterial population after 4 hours.

Indicate between which two integers the following root lies \( ?<\sqrt{13}< \) ?

e) \( \sqrt[2]{\left(\frac{49}{9}\right)^{11} \cdot\left(\frac{49}{9}\right)^{-4}:\left(\frac{98}{18}\right)^{6}: \frac{196}{36}+[3-(0, \hat{6}-1)]^{2}}= \)

Agar \( a=(\sqrt{3}+1)^{4} \) bo'lsa, \( a \cdot(1-\{a\}) \) ning qiymatini toping. Bu yerda \( \{a\}-a \) sonining kasr qismi. \( \begin{array}{llll}\text { A) } 1 & \text { B) } 81 & \text { C) } 54 & \text { D) } 16\end{array} \)
