This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Here is what I think: 1^0.25=1/1^4. just as x^2=k(k is any constant) has 2 solutions (whether it is within the range of real number or not), x^4=k should have 4 solutions. Think that you are solving an equation 1/x^4 = 1. i and 1 are both solutions (two out of the four) of the equation 1/x^4=1.

I totally agree that it has 4 solutions, but if we open x then it will have 1 as a solution of i. Although there maybe 3 more but 1 is also its solution right?

Hmm. Good. What if we write it as $(1^ \frac {1}{2} )^ \frac{1}{2}$ , then square root of 1 is -1. Then you will get the desired result. Your working is a result of false root. :-)

i can also be written as i^n×1/n and then i will have n roots. So now can we say that i has n values?

It's what Margaret was talking about but even if there is a false root this means 1 is a root of i irrespective of it being false or true.

Yup. That is root. (Although that is false)
