Question

(7ab)², 5ab•2a²k¹⁰b, (-3m²n²)³•(-2mn)²

Answer 1

1. (7ab)²

  (7ab)² = 7² * (a)² * (b)² = 49a²b²

2. 5ab * 2a²k¹⁰b:

  5ab * 2a²k¹⁰b = 10a³bk¹⁰

3. (-3m²n²)³ * (-2mn)²:

  (-3m²n²)³ * (-2mn)² = (-3)³ * (m²)³ * (n²)³ * (-2)² * (m)² * (n)² = -27m⁶n⁶ * 4m²n² = -108m⁸n⁸

Відповідь:

1. (7ab)² = 49a²b²

2. 5ab * 2a²k¹⁰b = 10a³bk¹⁰

3. (-3m²n²)³ * (-2mn)² = -108m⁸n⁸
