Answer:

X = -125

Answer 2

Answer:

The value of x is -125

Therefore x=-125

Step-by-step explanation:

Given that the expression is $(-5)^{-3}$

To solve the expression :

$(-5)^{-3}$

$=\frac{1}{(-5)^3}$ ( by using the property $a^{-m}=\frac{1}{a^m}$ )

$=\frac{1}{(-5)\times (-5)\times (-5)}$ ( expanding the power )

Let $x=(-5)\times (-5)\times (-5)$

$=\frac{1}{x}$

Now the value of x is $x=(-5)\times (-5)\times (-5)$

$=-125$

Therefore x=-125

The value of x is -125
