Simplifying Algebraic Expressions: (-4a^2b)(-3a^7b)/6a^7b^2+16a^2
This article will guide you through simplifying the algebraic expression (-4a^2b)(-3a^7b)/6a^7b^2+16a^2. We'll break down the steps involved and explain the key concepts used.
Step 1: Simplify the Numerator
- Multiplication of Monomials: Multiply the coefficients and add the exponents of like bases.
- (-4a^2b)(-3a^7b) = 12a^(2+7)b^(1+1) = 12a^9b^2
Step 2: Simplify the Denominator
- No simplification needed: The denominator is already in its simplest form, as there are no common factors that can be cancelled out.
Step 3: Combine the Simplified Numerator and Denominator
- Dividing Monomials: Divide the coefficients and subtract the exponents of like bases.
- 12a^9b^2 / 6a^7b^2 = (12/6)a^(9-7)b^(2-2) = 2a^2
Step 4: Combine the Simplified Result with the Remaining Term
- Adding Terms: The remaining term is 16a^2. Since both terms now have the same base and exponent (a^2), we can add their coefficients.
- 2a^2 + 16a^2 = (2+16)a^2 = 18a^2
Final Result
Therefore, the simplified form of the expression (-4a^2b)(-3a^7b)/6a^7b^2+16a^2 is 18a^2.
Key Concepts:
