Simplifying (a^-5)^2
In mathematics, simplifying expressions is a crucial skill. This involves using the rules of exponents to express the expression in its simplest form. Today, we'll tackle the simplification of (a^-5)^2.
Understanding the Rules
Before we dive into the simplification, let's review the essential rules of exponents we'll use:
- Product of Powers: a^m * a^n = a^(m+n)
- Power of a Power: (a^m)^n = a^(m*n)
- Negative Exponent: a^-n = 1/a^n
Simplifying (a^-5)^2
Now, let's apply these rules to our expression:
-
Apply the Power of a Power rule: (a^-5)^2 = a^(-5*2)
-
Simplify the exponent: a^(-5*2) = a^-10
-
Apply the Negative Exponent rule: a^-10 = 1/a^10
Therefore, the simplified form of (a^-5)^2 is 1/a^10.
Conclusion
Simplifying expressions like (a^-5)^2 involves understanding and applying the fundamental rules of exponents. By systematically applying these rules, we can arrive at a concise and easy-to-understand expression.
