Question

cube root of rational number​

Answer 1

Step-by-step explanation:

Definition of cube root of rational numbers : If x and a are two rational numbers such that x 3 = a then we say that x is the cube root of a and we write

∛a = x

We know that,

(3/4) 3 = 27/64 ⇒ ∛(27/64) = 3/4

(-4/11) 3 = -64/1331 ⇒ ∛(-64/1331) = -4/11
