Question

How do you simplify `3x ^ { 5} y ( 9x ^ { 2} - x ^ { 3} y ^ { 5} + 9y ^ { 5} )`?

Answer 1

See a solution process below:

Explanation:

To simplify this expression, multiply each term within the parenthesis by the term outside the parenthesis:

`color(red)(3x^5y)(9x^2 - x^3y^5 + 9y^5)`

`(color(red)(3x^5y) xx 9x^2) - (color(red)(3x^5y) xx x^3y^5) + (color(red)(3x^5y) xx 9y^5)`

`27x^7y - 3x^8y^6 + 27x^5y^6`
