Answer 1

Resposta:

Explicação passo-a-passo:

11)

a) √(81a²x⁶) =

√81√a²√x⁶ =

9ax³.

b) √[(25/16)a⁴b¹⁶] =

√(25/16)√a⁴√b¹⁶ =

(5/4)a²b⁸.

c) (- 1/3)x⁷y⁵ ÷ (5/4)xy =

(- 1/3)x⁷y⁵ / (5/4)xy =

- (4/15)x⁶y⁴.

d) (2/3)xy + (1/4)xy =

(8/12)xy + (3/12)xy =

(11/12)xy.

e) - (3/5)ab⁵ . (2/5)a²b³ =

- (6/25)a³b⁸.

f) [(- 2/3)x³y⁵]³ =

(- 2³/3³)x⁹y¹⁵ =

- (8/27)x⁹y¹⁵.
