When time is measured in days, the decay constant for a particular

When time is measured in days, the decay constant for a particular radioactive isotope is 0.14. Determine the time required for a confined sample of the isotope to fall to 80% of its original value. The time required for a confined sample of the isotope to fall to 80% of its original value is about (Do not round until the final answer. Then round to the nearest hundredth as needed.) days.
