Okay I am lost Please help me understand what they are asking?

Question

∛-8/27 I have to evaluate this it is 3 sqrt-8/27
√4/25 and evaluate this
√-121 and this I thought I was looking for one answer such as √-121 which would be 11i but I got these wrong so what is he looking for as an answer so lost.

Answer 1

The first one is the *cube* root of -8/27.
cuberoot(-8/27)
= cuberoot(-8) / cuberoot(27)
= -2/3*

*Technically there are also 2 imaginary roots to this too, so not sure if that is what they are looking for.

Next:
sqrt(4/25)
= sqrt(4) / sqrt(25)
= ±2/5 (two real roots)

sqrt(-121)
= sqrt(-1) * sqrt(121)
= i * sqrt(121)
= ±11i (two imaginary roots)
