Simplifying Algebraic Expressions: A Step-by-Step Guide
This article will guide you through simplifying the algebraic expression: (2x^5y^3)^3(4xy^4)^2/8x^7y^12
Let's break down the process step by step:
1. Expanding the Parentheses
First, we need to apply the power rule for exponents: (a^m)^n = a^(m*n) to expand the parentheses.
- (2x^5y^3)^3: This becomes 2^3 * (x^5)^3 * (y^3)^3 = 8x^15y^9
- (4xy^4)^2: This becomes 4^2 * (x)^2 * (y^4)^2 = 16x^2y^8
Now our expression looks like this: (8x^15y^9)(16x^2y^8)/8x^7y^12
2. Combining Like Terms
Next, we multiply the coefficients and add the exponents of the variables with the same base.
- 8 * 16 / 8 = 16
- x^15 * x^2 = x^17
- y^9 * y^8 = y^17
This gives us: 16x^17y^17 / 8x^7y^12
3. Simplifying the Expression
Finally, we divide the coefficients and subtract the exponents of the variables with the same base.
- 16 / 8 = 2
- x^17 / x^7 = x^10
- y^17 / y^12 = y^5
Therefore, the simplified expression is 2x^10y^5.
Summary
By following these steps, we have successfully simplified the complex algebraic expression. The key takeaways are:
- Apply the power rule for exponents to expand parentheses.
- Combine like terms by multiplying coefficients and adding exponents of the same base.
- Simplify the expression by dividing coefficients and subtracting exponents of the same base.
