Simplifying Expressions with Exponents
This article will guide you through simplifying the expression (4ab^3)(-5b^6)(2a^2).
Understanding the Properties of Exponents
Before we begin, let's refresh our memory on the properties of exponents that will be crucial in simplifying our expression:
- Product of powers: x^m * x^n = x^(m+n)
- Commutative Property: a * b = b * a
Step-by-Step Simplification
-
Rearrange the terms: Using the commutative property, we can rearrange the terms to group the coefficients and variables with the same base together.
(4ab^3)(-5b^6)(2a^2) = (4 * -5 * 2) * (a * a^2) * (b^3 * b^6)
-
Multiply the coefficients: (4 * -5 * 2) * (a * a^2) * (b^3 * b^6) = -40 * (a * a^2) * (b^3 * b^6)
-
Apply the product of powers rule: -40 * (a * a^2) * (b^3 * b^6) = -40 * a^(1+2) * b^(3+6)
-
Simplify: -40 * a^(1+2) * b^(3+6) = -40a^3b^9
Conclusion
Therefore, the simplified form of the expression (4ab^3)(-5b^6)(2a^2) is -40a^3b^9. By understanding the properties of exponents and applying them step-by-step, we can efficiently simplify complex expressions.
