Question 253242
Here is the question:
{{{(9x^2y/(-4x^3y^4)) * (16x^4y^2/(25xy))}}}
Simplify the left side of the product as
{{{(9x^(-1)y^(-3)/(-4)) * (16x^4y^2/(25xy))}}}
--
Simplify the right side of the product as
{{{(9x^(-1)y^(-3)/(-4)) * (16x^3y^1/(25))}}}
--
Multiply the numerators together as:
{{{144x^(2)y^(-2)/(-4) * 1/(25)}}}
--
multiply the denominators together as
{{{144x^(2)y^(-2)/(-100)}}}
reduce the coefficients to get
{{{-72x^(2)y^(-2)}}}
