Question

Simplify
21x^6 y^5
14x^2y^9

Answer 1

`(3x^(4) )/(2y^(4) )`

Explanation:

Factor out 7 from top and bottom :

`(7(3x^6y^5))/(7(2x^2y^9))`

Divide top and bottom by 7 :

`(3x^6y^5)/(2x^2y^9)`

Simplify :

`(x^6)/(x^4)=x^(2)`

Simplify :

`(y^5)/(y^9) = y^(-4) = (1)/(y^(4) )`

Collect everything together :

`(3x^(4) )/(2y^(4) )`

Hope this helped and have a good day
