The actual rate of learning on the calculator for r^4 of 0.375 is for example.. ?(?(0.375)) =0.75
But what if I want to find r^3 of 0.375, how would I work it out on the calculator?May 22, 2021 at 8:17 am #621394
You need a scientific calculator which will have a button on it for calculating the x’th root.
There is a scientific calculator in the CBE software that you can use, and this has that button.May 24, 2021 at 7:09 pm #621662
I’ve found a way to do it e.g
=0.70May 25, 2021 at 8:19 am #621692
That is fine. Taking something to the power of 1/3 is the same as taking the third root. (Just as taking something to the power of 1/5 is the same as taking the 5th root)
It doesn’t matter which you do (although if your calculator has a button that lets you take something to the power of 1/3 then it will also have a button that lets you take the third root 🙂 )May 25, 2021 at 8:23 pm #621765
No my calculator doesn’t allow me to do the root.
Thank you for your help…May 26, 2021 at 9:05 am #621791
You are welcome (it should be above the button that lets you take any power – you press the button that says ‘2nd’ on it, and then the power button to take an nth root)
