Answer:

0.5158

Step-by-step explanation:

The exponential decay of a given material is used to describe the process by which a material decreases in size and amount over a specific period of time. The material will decay with respect to its decay factor. Therefore, if the 10-hour decay factor is approximately 0.2661, the 5-hour growth/decay factor will be: (0.2661)^(5/10) = (0.2661)^0.5 = 0.5158.
