What is the value of 7 ^−3 ^ −1 for = −2 and = 4?
a. −224
b. 7/4096
c. 7(−8)^−4
d. −7/32

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

So the expression can be rewritten as

Now we observe that:

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
