WebExponential and Logarithmic functions. The doubling period of a bacterial population is 15 minutes. At time t=90 minutes, the bacterial population was 70000. What was the initial population at time t=0? WebThe logarithm operation is defined as the inverse of exponentials. For example, suppose we know bx = n; that is, we know that n is b to the power of x. In that case, we also know x = logb(n); that is, we say that x is the logarithm of n with the base b. Here are some examples of equations using logs: log3(27) = 3. log 3 ( 27) = 3. log2(16) = 4.

For example, we know that the following exponential equation is true: \displaystyle {3}^ {2}= {9} 32 = 9 In this case, the base is \displaystyle {3} … WebAug 12, 2024 · logarithm: The power (or exponent) to which one base number must be raised — multiplied by itself — to produce another number. For instance, in the base 10 system, 10 must be multiplied by 10 to produce 100. So the logarithm of 100, in a base 10 system, is 2. In base 10, the logarithm of 1,000 would be 3, the log of 10,000 would be … good morning 4 states joplin mo
