Answer 1

Resposta:

a) (a/5m)² =  a²/25m²

b) (7x/a)² =  49x²/a²

c) (3x/a²)² =  9x²/3a^4

d) (2a³/3x²)³ =  8a^9/27x^6

e) (2a²/x³)³ =  8a^6/x^9

f) (6c²/5)² =  36c^4/25

2) Calcule as Potências:

a) (2a³/m⁴)² =   4a^6/m^8

b) (a⁵/2b)³ =  a^15/8b³

c) (2m⁵/3)⁴ =  16m^20/81

d) (am⁴/c³)² =  a²m^8/c^6

e) (2x⁵/a³c³)² =  4x^10/a^¨6a^6

f) (m³/2n²)⁵ =  m^15/32n^10

 3) Calcule as Potencias

a) ( -2x/y)² =  4x²/y²

b) (-3x³/a⁶)² = 9x^6/a^12

c) (-5x⁴/2a³)³  = -125x^12/8a^9

d) (-2x/y)⁵ =  -32x^5/y^5

e) (-4x²/3y)² = 16x^4/9y²

f) (-2x²/ 3y³)⁴ =  16x^8/81y^12
