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
