Answer: A

Explanation:

Step 1:

apply power rules (dividing with powers can be expressed as subtracting the exponents to simplify

= x^(-3 - 2) y^(1 - -2) c^(8-7)

= x^-5 y^3 c

Step 2:

Substitute values

= 2^(-5) * 3^3 * -2

Step 3:

Simplify

= 2^(-5) is 1/(2^5)

= 1/32

= 3^3

= 27

= (1/32) * 27 * -2

= (27 * -2) / 32

LCD of 2 and 32 is 2, to convert to lowest terms

= (27 * -1) / 16

= -27/16
