Technetium-99m is used as a radioactive tracer for certain medical tests. It has a half-life of 1 day. Consider the equation where y = 15(4)^(-d) is the percent of Technetium-99m remaining d days after the test. Write a logarithmic expression that represents the number of days until only 25% remains.
