I am trying to use a fraction (one third in order to find the cube root of a number) for exponent value. Since I did not see a way to enter that I used the division (1 divided by 3) so the program is calculating the decimal value first and using that as the exponent/power. How do i tell the program I want the cube root.

Isn’t the cubic root and raising to the power of .3 the same?

No. That will not give the correct result. See screenshot with power 0.3 ![decimalexponent](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/a/fa4f3dd459279b9912118b3f8f7a5a5ee6ac1692.png)

Yes but .3 and 1/3 aren’t the same either.

1/3 = .3333333333333333333333333 repeating forever

</div>

So how does one find the cube root of a number in Thunkable?

I am using 1 divided by 3 for the exponent and then rounding the result. So far it seems to work.  
Thanks for responding.
