Question

Using the cubed root symbol, how do you represent the solution to x(3)=1/8? Please pick which one is the correct answer
Possible responses:

a. x = (3)√−1/8
x equals root index 3 Start Root negative Start Fraction 1 over 8 End Fraction End Root

b. x = √ 1/8
x equals Start Root Start Fraction 1 over 8 End Fraction End Root

c. x=− (3)√1/8
x equals negative root index 3 Start Root Start Fraction 1 over 8 End Fraction End Root

d. x = 3 √1/8

Answer 1

The correct choice is d. x = 3√(1/8), i.e. x = ∛(1/8) = 1/2.
