Step-by-step explanation:
∛(27a⁻⁶b³c²)
To simplify, first apply the cube root the each of the terms. Keep in mind this rule:
∛27 = 3 (because 3*3*3 = 27)
∛a⁻⁶ = =
=
∛b³ = =
= b
∛c² =
∛(27a⁻⁶b³c²)
=
Simplified form generally follows these rules:
No negative exponents
No fraction exponents
Keep in fractional form
