Question

What is the value of this expression when j = -2 and k = -1?

(jk^-2) * (j^-1 * j^-3)
A. -64
B. -1/2
C. 1/2
D. 64

Answer 1

The value of the expression when j = -2 and k = -1 is -1/8.

Step-by-step explanation:

To find the value of the expression when j = -2 and k = -1, we substitute the given values into the expression and perform the necessary calculations.

Expression: (jk^-2) * (j^-1 * j^-3)

Substituting j = -2 and k = -1:

(-2 * (-1)^-2) * ((-2)^-1 * (-2)^-3)

Simplifying:

(-2 * 1) * (1/(-2) * 1/(-8))

= -2 * (1 * 1/(-2 * -8))

= -2 * (1 * 1/16)

= -2 * (1/16)

= -1/8

Therefore, the value of the expression when j = -2 and k = -1 is -1/8.
