Question

19/28
simplify: $\frac{40x^{8}y^{2}}{8x^{4}y}$
$8x^{4}y$
$5x^{4}y$
$32x^{4}y^{3}$
$5x^{8}y^{2}$

Explanation:

Step1: Simplify the coefficients

$\frac{40}{8} = 5$

Step2: Simplify $x$-terms (subtract exponents)

$x^{8-4} = x^4$

Step3: Simplify $y$-terms (subtract exponents)

$y^{2-1} = y^1 = y$

Step4: Combine all simplified parts

$5 \times x^4 \times y$

Answer:

B. $5x^4y$
