Answer: 
Step-by-step explanation:
 For this exercise it is important to remember the following:
 
 Given the following expression:
 
 You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:
 1. Replace  with
 with  and simplify:
 and simplify:
 
 2. Descompose 12 into its prime factors:
 
 3. Substitute into the expression:
 
 4. Since ![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da) , you can simplify it:
, you can simplify it:
 
 
        
             
        
        
        
Ok so
Knowing that 1 metre consists of 100cm,
You can conclude and agree that 8 cm is 8/100, correct?
Now, when converting fractions to decimals, it makes it easier out of 100 or 10. Since it's out of 100 already, you take the amount of zero's in 100 (two) and you move the decimal point (2) places to the <em /><u>left<em /></u> 
This gives you 0.08
So the fraction is 8/100, which then can be simplified to 4/50, then to 2/25
and the decimal is 0.08.
