Answer with Step-by-step explanation:
We are given a variable b
We have to state the additive property of zero using the variable b.
Additive property of zero: It states that when any number b is added to zero then we get sum is equal to number itself.
Mathematical representation:

Suppose, a number b=9
Then, 9+0=9
0+9=9
This property is called additive property of zero because when 9 is added to 0 then we get sum equals to 9.
Answer: Its a
Step-by-step explanation:
Answer: 1/6^3 AND 1/216
Step-by-step explanation:
A negative number always goes to the denominator to become positive.
Both the numerator and denominator can be divided by three, so the simplest form is
