Iridium-192 is an isotope of iridium and has a half life of 73.83 days. if a laboratory experiment begins with 100 grams of iridium-192, the number of grams, a, of iridium-192 present after t days would be a= 100(1/2)^t/73.83. which equation approximates the amount of iridium-192 present after t days?

Step-by-step explanation:

It does say an approximate equation so we could play with law of exponents a little especially if you don't like that fraction in the exponent.

I'm going to put (1/2)^(1/73.83) into my calculator.

This gives me approximately: 0.990655512.

So maybe that is what you are looking for.
