A value with zero uncertainty and an infinite number of significant figures is called an exact number.
A value that is known with confidence is called an exact number. In other terms, an exact integer has an infinite number of significant digits and zero uncertainty. It is impossible to simplify or reduce an exact number. A value with zero uncertainty and an infinite number of significant figures is called an exact number.

Answer:
a) 320: two significant figures.
b) 2,366: four significant figures.
c) 73.0: three significant figures.
d. 532.5: four significant figures.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to write each number by knowing we move the decimal places to the right as much as the exponent is, and also, we count every figure, even zeros, because they are to the right of the first nonzero digit:
a) 320: two significant figures because the rightmost zero is not preceded o followed by a decimal place.
b) 2,366: four significant figures.
c) 73.0: three significant figures, because the zero is followed by the decimal place.
d. 532.5: four significant figures.
Regards!
