18
Step-by-step explanation:
To continue where you left off, ...

The square root of 324 is 18.
Answer=Order of operations
The order of operations (which we use PEMDAS to help us remember) tells you which operation to do first.
-3 -1 i believe is your answer
The answer $456 because I guessed
Answer:
The pair which are inverse of each other are:
Option: C

Step-by-step explanation:
Two functions f(x) and g(x) are said to be inverse of each other if:
fog(x)=gof(x)=x
i.e. the composition of two functions give identity no matter what the order is.
A)
and 
Now we calculate fog(x):

Hence, option: A is incorrect.
B)

Now we calculate fog(x):

Hence, option: B is incorrect.
D)
![f(x)=9+\sqrt[3]{x}\ and\ g(x)=9-x^3](https://tex.z-dn.net/?f=f%28x%29%3D9%2B%5Csqrt%5B3%5D%7Bx%7D%5C%20and%5C%20g%28x%29%3D9-x%5E3)
Now we calculate fog(x):

![fog(x)=9+\sqrt[3]{9-x^3}\neq x](https://tex.z-dn.net/?f=fog%28x%29%3D9%2B%5Csqrt%5B3%5D%7B9-x%5E3%7D%5Cneq%20x)
Hence, option: D is incorrect.
C)

Now we calculate fog(x):


Similarly,

Hence, option: C is the correct option.
