Expand by using the distributive property:

[tex]
2 x^4 y^4\left(x^{-1} y-2 x^2 y^{-2}\right)
[/tex]


Sagot :

Sure! To expand the expression [tex]\(2 x^4 y^4\left(x^{-1} y-2 x^2 y^{-2}\right)\)[/tex] using the distributive property, follow these steps:

1. Distribute the terms inside the parentheses to each term outside:
[tex]\[ 2 x^4 y^4 \cdot x^{-1} y - 2 x^4 y^4 \cdot 2 x^2 y^{-2} \][/tex]

2. Simplify each term individually:

- For the first term [tex]\(2 x^4 y^4 \cdot x^{-1} y\)[/tex]:
[tex]\[ 2 x^4 y^4 \cdot x^{-1} y = 2 \left(x^4 \cdot x^{-1}\right) \left(y^4 \cdot y\right) \][/tex]
Using the law of exponents where [tex]\(a^m \cdot a^n = a^{m+n}\)[/tex]:
[tex]\[ 2 \left(x^{4-1}\right) \left(y^{4+1}\right) = 2 x^3 y^5 \][/tex]

- For the second term [tex]\(2 x^4 y^4 \cdot 2 x^2 y^{-2}\)[/tex]:
[tex]\[ 2 x^4 y^4 \cdot 2 x^2 y^{-2} = 2 \cdot 2 \left(x^4 \cdot x^2\right) \left(y^4 \cdot y^{-2}\right) \][/tex]
Simplify the constants:
[tex]\[ 4 \left(x^{4+2}\right) \left(y^{4-2}\right) = 4 x^6 y^2 \][/tex]

3. Combine the simplified terms:
Collect the results:
[tex]\[ 2 x^3 y^5 - 4 x^6 y^2 \][/tex]

Thus, the expanded expression is:
[tex]\[ -4 x^6 y^2 + 2 x^3 y^5 \][/tex]

That’s the final expanded form of the given expression using the distributive property.
