Please someone help me with my work i will give you brainly if it is correct :)

Answer 1

Answer:

$\frac{3x^{4} }{2y^{4} }$

Step-by-step explanation:

$\frac{21x^{6}y^{5} }{14x^{2}y^{9} }$

→ First simplify the numbers

$\frac{3x^{6}y^{5} }{2x^{2}y^{9} }$

→ Now simplify the x powers, remember when dividing indices, you subtract them away from each other so,

$\frac{3x^{4}y^{5} }{2y^{9} }$

→ Now simplify the y powers, remember when dividing indices, you subtract them away from each other so,

$\frac{3x^{4} }{2y^{4} }$
