Question

Select the correct answer. Evaluate the following expression when x = -4 and y = 4. A. B. C. D.

Answer 1

The value of given expression when x=-4 and y=4 is 1250.

The expression is missing in the question which is $\dfrac{x^6-x}{4y}$.

We have to solve it for x= -4 and y = 4.

Now putting the value of x and y we get,

$\dfrac{x^6-x}{4y}=\dfrac{(-4)^6-(-4)}{4}$

$\dfrac{x^6-x}{4y}=\dfrac{4096+4}{4}$

$\dfrac{x^6-x}{4y}=1250$

Hence the value of given expression when x=-4 and y=4 is 1250.
