Determine the value of the ?

goblinko [34]

Answer:

$x^{2} y^{3}$

Step-by-step explanation:

Using the Quotient rule:

$\frac{a^{m}}{a^{n}} = a^{m - n}$

We can subtract the exponents of x and y:

$\frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{(6 - 4)} y^{(10 - 7)}$

Therefore, $\frac{x^{6} y^{10}}{x^{4} y^{7}} = x^{2} y^{3}$
