Answer:
![\frac{2x^{2} }{3y^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E%7B2%7D%20%7D%7B3y%5E%7B2%7D%20%7D)
Step-by-step explanation:
![\frac{30x^{3} }{45xy^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B30x%5E%7B3%7D%20%7D%7B45xy%5E%7B2%7D%20%7D)
You can solve this easily like this.
× (x³ ÷ x ) × ( 1 ÷ y² )
× x³ ⁻ ¹ × 1 ÷ y²
× x² × 1 ÷ y²
You can write this altogether like this.
![\frac{2x^{2} }{3y^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E%7B2%7D%20%7D%7B3y%5E%7B2%7D%20%7D)
Hope this helps you :-)
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab +b²
a = y & b = 10
(y + 10)² = y² + 2 *y*10 + (10)²
= y² + 20y + 100
