Question

a) (+2x)² c) (+2x²y)³ e)(-5x⁴y)¹
b) (-3a²)³ d)(-xy²)⁴ f)(-1/2a)²​

Answer 1

a) (+2x)² = (2x)(2x) = 4x²

b) (-3a²)³ = (-3a²)(-3a²)(-3a²) = -27a⁶

c) (+2x²y)³ = ) (+2x²y)(+2x²y)(+2x²y) = 8x⁶y³

d)(-xy²)⁴ = (-xy²)(-xy²)(-xy²)(-xy²) = +x⁴y⁸

e)(-5x⁴y)¹ = -5x⁴y

f)(-1/2a)² = (-1/2a)(-1/2a) =+2/4a²

❤️ Boa semana ❤️
