Answer:
D
Step-by-step explanation:
So we have the expression:

And we want to evaluate it when x=25, y=10, w=11, and z=18.
So, substitute these values for the variables:

First, subtract within the parentheses:

Square 15:

Now, multiply the terms on the right. 10 times 11 is 110:

Multiply:

Finally, add:

So, our answer is D.
And we're done!
To simplify this, you would have to turn b^-2 into a positive exponent.
To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2
3a^4 b^-2 c^3 / b^-2
Then we get the answer:
3a^4 c^3
------------
b^-2
I have a picture to clarify!
I hope this helped, let me know if you don't understand! ^.^
Divide 6 by -8 to get the variable alone!
6/-8 < division< equation
