Which is the value of this expression when j = negative 2 and k = negative 1?

(StartFraction j k Superscript negative 2 Baseline Over j Superscript negative 1 Baseline k Superscript negative 3 Baseline EndFraction) cubed

-64

Step-by-step explanation:

The expression is written as

We need to apply the rules of power of power in algebra:

Also, we apply the quotient of variables

Let's simplify the given expression

For j=-2 and k=-1

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
