Question

Marie factored 11x^3y^5 as (8x^3)(3y^5). Stanley factored 11x^3y^5 as (11xy)(x^2y^4). Which of them factored 11x^3y^5 correctly?

Answer 1

Answer:

Stanley factored it correctly.

Step-by-step explanation:

$11x^3y^5$

We are given that Marie and Staley factored the above expression as follows and we are to determine who factored it correctly:

Marie: $11x^3y^5$ ---> $(8x^3)(3y^5)$

$(8x^3)(3y^5)$ = $24x^3y^3$ so this is wrong.

Stanley: $11x^3y^5$ ---> $(11xy)(x^2y^4)$

$( 1 1 x y ) ( x ^ 2 y ^ 4 )$ = $1 1 x ^ 3 y ^ 5$

Therefore, Stanley factored it correctly.
