# Question #c2e90

##### 1 Answer

#### Answer:

The answer is **(b)**

#### Explanation:

The first thing to keep in mind when dealing with **significant figures** is that **all nonzero digits** are * significant*.

This means that right from the start, you know that your number has *at least* two sig figs,

#0.00color(blue)(3)00color(blue)(5)0 -># two nonzero digits

Another important thing to remember is that **all zeros** that appear between **two nonzero digits** are * significant*. As you can see, you have two zeros that appear between the two nonzero digits, which will bring the number of sig figs to

*four*

#0.00color(blue)(3)color(red)(00)color(blue)(5)0 -># two nonzero digits and two zeros that appear between those digits

Finally, you should remember that **trailing zeros** in a number that **contains a decimal point** are * significant*.

Your number, which contains a decimal point, has **one** trailing zero, which will bring the number of sig figs to *five*.

#0.00color(blue)(3)color(red)(00)color(blue)(5)color(green)(0) -># two nonzero digits, two zeros that appear between those digits, and one trailing zero

Therefore, the answer will be **(b)**
