If
z^3=-64
then:
z=(-64)^(1/3)
z=-4
The answers are 1 1/6 and -1/6!
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1
You can check your work by multiplying 13.1 by 13.1 which equals 170.3
I try to explain the problem and give the answer, I hope this helps!
