Answer:

  • See below

Explanation:

#1

  • 1/16a² - ab + 4b² =
  • (1/4a)² - 2(1/4a*2b) + (2b)² =
  • (1/4a - 2b)²

#2

  • 9y² + c²d² + 6cdy =
  • (3y)² + 2(3y)(cd) + (cd)² =
  • (3y + cd)²

#3

  • 9/25a⁶b² - a⁴b⁴ + 25/36a²b⁶ =
  • (3/5a³b)² - 2(3/5a³b)(5/6ab³) + (5/6ab³)² =
  • (3/5a³b - 5/6ab³)²
