Answer 1

1a) (2a)² = 4a²
b) (3xy)³ = 27x³y³
c) (-2ab)⁴ = 16a⁴b⁴
d) (4a²b²)² = 16a⁴b⁴
e) -3(x²y)³ = -3(x^6 y³)
= -3x^6 y³
f) -(2pq)⁴ = - 16p⁴q⁴
g) ½(2xy)² = ½(4x²y²)
= 2x²y²
h) a(ab²)³ = a(a³b^6)
= a⁴ b^6

2a) (x + 2)² = x² + 4x + 4
b) 3(2x - 1)³
= 3(2x - 1)²(2x - 1)
= 3(4x² - 4x + 1)(2x - 1)
= 3(8x³- 8x²+4x - 4x²+4x - 1)
= 3(8x³ - 12x² + 8x - 1)
= 24x³ - 36x² + 24x - 3
