Potencias con exponetes enteros. La edad de una micro bacteria J es de 1/3^-3 dias. a)¿Cuál es la edad total de tres micro bacterias? b)Una micro bacteria M vive la tercera parte de la vida de la micro-bacteria J. ¿Cuántos días vive la micro bacteria M?

a) Age of the three microbacteria J=0.00099 days

b) Age of the microbacteria M=0.00011 days

Step-by-step explanation:

a)We first calculate the age of a single microbacterium J, as follows:

Age of microbacteria J=(1/3)^-3=0.00033 days

The total age of the three microbacteria J is equal to:

Age of the three microbacteria J=3x0.00033=0.00099 days

b) If a microbacteria M lives the third part of what the microbacterium J lives, only the age of the microbacteria J must be divided by three, thus:

Age of microbacteria M=0.00033/3=0.00011 days
