Select the correct answer.

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

[tex]\frac{12 z^9 y^4}{6 z^8 y^2}[/tex]

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



Answer :

To simplify the expression [tex]\(\frac{12 z^9 y^4}{6 z^8 y^2}\)[/tex], we need to break it down into simpler steps.

1. Simplify the coefficients:
[tex]\[ \frac{12}{6} = 2 \][/tex]

2. Simplify the [tex]\(z\)[/tex] terms using the laws of exponents:
[tex]\[ \frac{z^9}{z^8} = z^{9-8} = z^1 = z \][/tex]

3. Simplify the [tex]\(y\)[/tex] terms using the laws of exponents:
[tex]\[ \frac{y^4}{y^2} = y^{4-2} = y^2 \][/tex]

Combining these results, the simplified form of the expression is:
[tex]\[ 2 z y^2 \][/tex]

Therefore, the correct answer is:

D. [tex]\(2 z y^2\)[/tex]
