Therefore 10 ^ 2 = 100 which is true :) As a more general rule Log a ( b ) = Log ( a ^ b ) In chemistry log base 10 is used almost all the time so: a will always = 10. edit: Just saw that in this video Log base e is used and not log base 10. i.e the inverse of Log base 10 ( b ) = 10 ^ b.
WebSep 12, 2024 · How do you calculate the half-life of a drug? Half life. The half-life of a drug is is the period of time required for its concentration or amount in the body to be reduced by exactly one-half. Example 2. Drug B has a half-life of 3 hours. 6hr = 2 half − life = 1800 ÷ 2 = 900 / 9hr = 3 half − life = 900 ÷ 2 = 450 /. 40 − 32 = 8ℎ = 480.
