Prehistoric cave paintings were discovered in a cave in france. the paint contained 24 %24% of the original carbon-14. use the exponential decay model for carbon-14, upper a equals upper a 0 e superscript negative 0.000121 ta=a0e−0.000121t, to estimate the age of the paintings. the paintings are approximately 1179411794 years old. (round to the nearest integer.) question is complete.

t = 11,794 years

Step-by-step explanation:

If you are looking for a confirmation that your answer is correct, it is.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

your answer would be 12
