Which expression is equivalent to [tex]\frac{60 x^{20} y^{24}}{30 x^{10} y^{12}}[/tex]?

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

B. [tex]2 x^{10} y^{12}[/tex]

C. [tex]30 x^2 y^2[/tex]

D. [tex]30 x^{10} y^{12}[/tex]



Answer :

To solve the expression [tex]\(\frac{60x^{20}y^{24}}{30x^{10}y^{12}}\)[/tex], we need to simplify both the numerical coefficient and the exponents of [tex]\(x\)[/tex] and [tex]\(y\)[/tex] individually.

### Step 1: Simplify the numerical coefficient

The coefficient in the numerator is 60, and the coefficient in the denominator is 30. We simplify this as follows:
[tex]\[ \frac{60}{30} = 2 \][/tex]
So, the simplified coefficient is 2.

### Step 2: Simplify the exponent of [tex]\(x\)[/tex]

The exponent of [tex]\(x\)[/tex] in the numerator is 20, and in the denominator, it is 10. To simplify the exponents of [tex]\(x\)[/tex], we subtract the exponent in the denominator from the exponent in the numerator:
[tex]\[ 20 - 10 = 10 \][/tex]
So, the simplified exponent of [tex]\(x\)[/tex] is [tex]\(10\)[/tex].

### Step 3: Simplify the exponent of [tex]\(y\)[/tex]

The exponent of [tex]\(y\)[/tex] in the numerator is 24, and in the denominator, it is 12. To simplify the exponents of [tex]\(y\)[/tex], we subtract the exponent in the denominator from the exponent in the numerator:
[tex]\[ 24 - 12 = 12 \][/tex]
So, the simplified exponent of [tex]\(y\)[/tex] is [tex]\(12\)[/tex].

### Step 4: Combine the simplified results

Combining the simplified coefficient and exponents, the expression [tex]\(\frac{60x^{20}y^{24}}{30x^{10}y^{12}}\)[/tex] simplifies to:
[tex]\[ 2x^{10}y^{12} \][/tex]

Therefore, the expression equivalent to [tex]\(\frac{60x^{20}y^{24}}{30x^{10}y^{12}}\)[/tex] is:
[tex]\[ 2x^{10}y^{12} \][/tex]

The correct choice is:
[tex]\[ \boxed{2 x^{10} y^{12}} \][/tex]
