Question

Simplify the following
(3a 2b ×2a 6b)

Answer 1

3a 2b ×2a 6b = 72a²b² = 72× (ab)²

Explanation:

3a 2b ×2a 6b = (3 × 2)×(a × b) × (2 × 6)×(a × b) [commutative property]

= (6×ab) × (12×ab) [associative property]

= (6×12) × (ab×ab) [commutative + associative]

= (72) × (ab)²

= 72× (ab)²

= 72a²b² [exponent property]
