What is the value of 12x^-3 y-1 for x=-1 and y=5<br> A.-12/5<br> B.-180<br> C.-60<br> D.-5/12

Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

$12x^{-3} y^{-1}$

When x = -1, the expression becomes

$12 * -1^{-3} y^{-1}$

Evaluate the exponent

$- 12 y^{-1}$

When y = 5, the expression becomes

$- 12 * 5^{-1}$

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
