Question 314943: 1. Assume that the number of viruses present in a sample is modeled by the exponential function "f(t)=10^t", where t is the elapsed time in minutes. How would you apply logarithms to determine when the sample will grow to 5 billion viruses?
2. Show how to solve the exponential equation 5.000,000,000=10^t

This is the same question.
Use logarithms to solve.
10%5Et=5000000000
log%28%2810%5Et%29%29=log%28%285000000000%29%29
t=9.699 minutes.
