We start with the expression (−32)−53. According to the negative exponent rule, we can rewrite this as:
(−32)−53=(−32)531
Step 2: Simplify the Fractional Exponent
Next, we need to evaluate (−32)53. This can be broken down into two parts: first, we take the fifth root of −32, and then we raise the result to the power of 3:
(−32)53=((−32)51)3
Step 3: Calculate the Fifth Root and Raise to the Power
The fifth root of −32 is −2 because (−2)5=−32. Therefore, we have:
(−32)53=(−2)3=−8
Substituting this back into our expression gives:
(−32)−53=−81=−0.125
Final Answer
Thus, the simplified form of (−32)−53 is:
−0.125
