Simplifying Algebraic Expressions: (3b^-2)^2(a^2b^4)^3
This article will guide you through simplifying the algebraic expression (3b^-2)^2(a^2b^4)^3. We will utilize the rules of exponents to break down the expression step by step.
Understanding the Rules of Exponents
Before we begin, let's review some key rules of exponents:
- Product of powers: x^m * x^n = x^(m+n)
- Power of a power: (x^m)^n = x^(m*n)
- Power of a product: (x*y)^n = x^n * y^n
- Negative exponent: x^-n = 1/x^n
Simplifying the Expression
-
Apply the power of a power rule:
- (3b^-2)^2 = 3^2 * (b^-2)^2 = 9b^-4
- (a^2b^4)^3 = (a^2)^3 * (b^4)^3 = a^6 * b^12
-
Combine the results from step 1:
- 9b^-4 * a^6 * b^12
-
Apply the product of powers rule:
- 9 * a^6 * b^(-4+12)
-
Simplify the exponents:
- 9a^6b^8
Final Result
The simplified form of the expression (3b^-2)^2(a^2b^4)^3 is 9a^6b^8.
