Answer:
8.39
Step-by-step explanation:
The significant figures are the numbers that follow the decimal point and have some value for the calculation we are doing.
In the case of the number 26.4, this has a significant figure, which is the number that is after the decimal point, that is, the number 4.
In the case of number 8.39, this has two significant figures that are three and nine.
If a quantity has a greater number of significant figures, it means that it is the most accurate measure. In this case, the most accurate measure is given by the number 8.39 because it has two significant figures.
