 Question 27166: Assume that the number of viruses present in a sample is modeled by the exponential function "f(t) = 10t", where t is the elapsed time in minutes. How would you apply logarithms to determine when the sample will grow to 5 billion viruses? ~I am not sure how to answer this question...can someone please help me?! Thank you!~Answer by josmiceli(9697)   (Show Source): You can put this solution on YOUR website!Your equation is You want to know when f(t) = 5 billion or in scientific notation so Take the log of both sides use the rules log(a*b*c* ... ) = log(a) + log(b) + log(c) + ... and log(10^k) = k
