a)√9a²=

b)√64m²n⁶=

c)√25a⁴x⁶y¹⁰=

d)∛27x¹²y¹⁵=

e)∛64a³b⁶c¹²=

f)∛-27x³y⁶=

Answer 1

a) √9*a² = √9 * √a² = ₃ *a = 3a

b) √64m²n⁶ = √64 * √m² * √n⁶ = 8 * m * n³ = 8mn³

c) √25a⁴x⁶y¹⁰ = √25 * √a⁴ * √x⁶ * √y¹⁰ = 5 *a² *x³ * y⁵ = 5a²x³y⁵

d) ∛27x¹²y¹⁵ = ∛27 * ∛x¹² * ∛y¹⁵ = 3 * x⁴ * y5 = 3x⁴y⁵

e) ∛64a³b⁶c¹² = ∛64 * ∛a³ * ∛b⁶ * ∛c¹² = 4 * a * b² * c⁴ = 4ab²c⁴

f) ∛-27x³y⁶ = ∛-27 * ∛x * ∛y⁶ = -∛27 * ∛x³ * ∛y⁶ = -3 * x * y² = 3xy²
