Question

If x = −1 × −1 × −1 × −1 × ... 55 times, y = −2 × −2 × −2 , then xy​

Answer 1

Answer:

x = −1 × −1 × −1 × −1 × ... 55 times

x = $-1^{55}$

x = -1 because a negative number to the odd power is always a negative power

y = −2 × −2 × −2

y= -8

Now, xy= -1 × -8 = 8

Answer 2

x = −1 × −1 × −1 × −1 × ... 55 times

x = -1^{55}−1

55

x = -1 because a negative number to the odd power is always a negative power

y = −2 × −2 × −2

y= -8

Now, xy= -1 × -8 = 8

it is correct
