1) (5b)² = 25b²25b² + 15/5b² + 3= 25b² + 3 + 3= 25b² + 6Answer: 25b² + 6
2) (5a²)³ = 125a⁶(6b)² = 36b²(30a³b)² = 900a⁶b²
Answer: 5
1) (5b)² = 25b²
25b² + 15/5b² + 3
= 25b² + 3 + 3
= 25b² + 6
Answer: 25b² + 6
2) (5a²)³ = 125a⁶
125a⁶ × 36b² / 900a⁶b²(6b)² = 36b²
(30a³b)² = 900a⁶b²
= 4500a⁶b² / 900a⁶b²
= 5
Answer: 5
