Question

o celula se divide in 2  noi celule in doua ore. determinati numarul de celule care se formeaza in 72 de ore, pornin d de la doua celule care se divid

Answer 1

1 celula se divide in 2 ore⇒$C_{2}$=2 celule
dupa 4 ore⇒$C_{4}$=4
6⇒$C_{6}$=8
8⇒$C_{8}$=16⇒$C_{n}$=$2^{ \frac{n}{2} }$
dupa 72 ore o celula se divide in $C_{72}$=$2^{ \frac{72}{2} }$=$2^{36}$
2 CELULE SE DIVID IN 72 ORE IN  2·$2^{36}$=$2^{37}$ CELULE
