Question

A) (+2x³)²

B)(-3a⁴)³

C)(+5x³y)³

D)(-x²y³)⁴

E)(-1_2a³)5

Answer 1

A) (+2x³)² = 2² (x³)² = 4 x^6

B)(-3a⁴)³ = (-3)³ (a⁴)³ = -27 a¹²

C)(+5x³y)³ = 5³ (x³)³ y³ = 125 x^9 y³

D)(-x²y³)⁴ = -x^8 y¹²

E)(-1/2 a³)^5 = -1/2^5 a^15 = -a^15/2^5

Answer 2

Olá...

a) (+ 2x³)²  = 2²(x³)² = 4x²ˣ³ = 4x⁶

b) (- 3a⁴)³  = (- 3)³(a⁴)³ = - 27a⁴ˣ³ = - 27a¹²

c) (+ 5x³y)³  = 5³(x³)³y³ = 125x³ˣ³y³ = 125x⁹y³

d) (- x²y³)⁴ = (x²)⁴(y³)⁴ = x²ˣ⁴y³ˣ⁴ = x⁸y¹²

e) (- 1/2a³)⁵ = (- a³/2)⁵ = - (a³)⁵/2⁵ = - a³ˣ⁵/2⁵ = - a¹⁵/32

Espero ter ajudado.
