Select the correct answer.

Which expression is equivalent to the given expression? Assume the denominator does not equal zero.

[tex]\[ \frac{12 x^9 y^4}{6 x^9 y^3} \][/tex]

A. [tex]\[ 2 x^3 y^2 \][/tex]

B. [tex]\[ \frac{2}{x^8 y^2} \][/tex]

C. [tex]\[ \frac{2}{x^2 y^2} \][/tex]

D. [tex]\[ 2 x^6 y^2 \][/tex]



Answer :

To simplify the expression [tex]\(\frac{12 x^9 y^4}{6 x^9 y^3}\)[/tex], follow these steps:

1. Simplify the Constants:

[tex]\[ \frac{12}{6} = 2 \][/tex]

2. Simplify the [tex]\(x\)[/tex] Terms:

Since [tex]\(x^9\)[/tex] appears in both the numerator and the denominator, we can write:

[tex]\[ \frac{x^9}{x^9} = x^{9-9} = x^0 = 1 \][/tex]

3. Simplify the [tex]\(y\)[/tex] Terms:

Since [tex]\(y^4\)[/tex] is in the numerator and [tex]\(y^3\)[/tex] is in the denominator, we subtract the exponent in the denominator from the exponent in the numerator:

[tex]\[ \frac{y^4}{y^3} = y^{4-3} = y^1 = y \][/tex]

Putting it all together, the simplified expression is:

[tex]\[ 2 \cdot 1 \cdot y = 2y \][/tex]

So, the equivalent expression is:

[tex]\[ 2y \][/tex]

Now, let's compare this with the given options:

A. [tex]\(2 x^3 y^2\)[/tex]
B. [tex]\(\frac{2}{x^8 y^2}\)[/tex]
C. [tex]\(\frac{2}{x^2 y^2}\)[/tex]
D. [tex]\(2 x^6 y^2\)[/tex]

None of the options exactly match our simplified expression [tex]\(2y\)[/tex]. There seems to be a mistake in the provided answer choices since the correct simplified form, based on my calculations, is indeed [tex]\(2y\)[/tex]. If the correct answer were present, it would be labeled as [tex]\(2y\)[/tex].
