1. There are two whole numbers x and y, such that x raised to power of y is equal to y raised to the power of x. Find the values of x and y

x and y can both equal 1

Step-by-step explanation:

Since we have:

And we know that they equal each other, 1 should be the best answer.

1¹ = 1¹

1 = 1

Step-by-step explanation:

When we input x as 1, and y as 1 we can see that they are equal.

When we input x as 2, and y as 2 we can see that they are also equal.

When we input x as -1, and y as -1 we can see that they are also equal.

When we input x and y as 0 it is also equal.

C(-1,1)

or

C(-5,3), C(1,5)

Step-by-step explanation:

If points A, B, C and D are four consecutive vertices of the parallelogram ABCD, then AB||DC

Let C has coordinates (x,y), then

C(-1,1)

If points A, B, C  and D are not necessarily consecutive vertices, then C can be placed at (-5,3) or (1,5) (see attached diagram)
