Answer:
17188 years
Explanation:
Given that;
0.693/t1/2 = 2.303/t log (Ao/A)
Where;
t1/2 = half life of carbon -14
t = time taken
Ao = activity of a living sample
A activity of the artifact
0.693/5730 = 2.303/t log (32/4)
1.21 * 10^-4 = 2.303/t * 0.9031
1.21 * 10^-4 = 2.0798/t
t = 2.0798/1.21 * 10^-4
t = 17188 years
