Simplifying Algebraic Expressions: (3d^-4)(5d^8)
This article will walk you through the steps of simplifying the algebraic expression (3d^-4)(5d^8).
Understanding the Rules
To simplify this expression, we'll utilize the following rules of exponents:
- Product of powers: When multiplying exponents with the same base, you add the powers.
- Example: x^m * x^n = x^(m+n)
- Negative exponents: A term with a negative exponent in the numerator can be rewritten with a positive exponent in the denominator.
- Example: x^-n = 1/x^n
Simplifying the Expression
-
Rearrange the terms:
(3d^-4)(5d^8) = (3 * 5)(d^-4 * d^8) -
Apply the product of powers rule: (3 * 5)(d^-4 * d^8) = 15d^(-4+8)
-
Simplify the exponents: 15d^(-4+8) = 15d^4
Final Answer
The simplified form of the expression (3d^-4)(5d^8) is 15d^4.
