Answer:
final answer is 6/(y^8)
Step-by-step explanation:
(3y^-4) = 3/(y^4)
(2y^-4) = 2/(y^4)
3*2 = 6
Add exponents y^4+y^4 = y^8
hence 6 / (y^8)
In the question, the given expression is

And we have to find the equivalent expression to the given expression .
First we remove the parenthesis

Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get

And that's the required equivalent expression .
Answer:
J
Step-by-step explanation:
C would be the correct answer
A would mean that 6=3*18, which is incorrect
B would mean that 3=6*18 which is also incorrect
C would mean that 18=6*3 which is CORRECT
D would mean that 18=6*2 which is also incorrect
Therefore, C would be the correct answer
