Answer:
7/11
Step-by-step explanation:
If x and a are two rational numbers such that x³= a then we will say that x is the cube root of a and we will write - ³√a
Thus, to find the cube root of any number we use the formula -
∛(a/b) = (∛a)/(∛b)
Thus,
-686/-2662
= 343/1331
= (∛343)/(∛1331)
= (∛7 x 7 x 7)/(∛11 x 11 x 11 )
= 7/11
Thus the cube root of 686/2882 is 7/11
