To simplify (y⁵ − 9x⁴)², we can use the formula for the square of a binomial:

(a - b)² = a² - 2ab + b²

In this case, a is y⁵ and b is 9x⁴. Substituting these values into the formula, we get:

 (y⁵ − 9x⁴)² = ( y⁵)² - 2(y⁵)( 9x⁴) + (9x⁴)²
              = y¹⁰ − 18x⁴y⁵ + 81x⁸  

Therefore, the simpl...
