Simplifying the Expression (-5cd-4)(2cd^2)^2
This article will guide you through simplifying the expression (-5cd-4)(2cd^2)^2.
Understanding the Expression
The expression consists of two parts:
- (-5cd-4): This is a binomial (an expression with two terms) with variables c and d.
- (2cd^2)^2: This is a monomial (an expression with one term) with variables c and d, raised to the power of 2.
Simplifying the Expression
To simplify the expression, we will follow the order of operations (PEMDAS/BODMAS):
-
Parentheses/Brackets:
- First, we need to simplify the expression within the parentheses (2cd^2)^2. Applying the power rule of exponents, we square each term inside the parentheses: (2cd^2)^2 = 2^2 * c^2 * (d^2)^2 = 4c^2d^4
-
Multiplication:
- Now, we have simplified the expression to: (-5cd-4)(4c^2d^4). To multiply these two expressions, we use the distributive property, multiplying each term in the first binomial by the second monomial:
(-5cd)(4c^2d^4) + (-4)(4c^2d^4)
-
Simplifying Terms:
- Finally, we multiply the coefficients and combine the variables: -20c^3d^5 - 16c^2d^4
Result
Therefore, the simplified expression of (-5cd-4)(2cd^2)^2 is -20c^3d^5 - 16c^2d^4.
