Please does any one know what I should press on my calculator .
I have an equation R^3 = 0.343
R = 70%What should I do ? I use Texas Instrument calculator ! Any help I will appreciate because this might just simply be a problem to me on my exams .
You need to take the third root of 0.343.
Assuming you have a scientific calculator, then you will have a button with x’th root on it, and maybe also a button specifically for third root.
You need to look at the manual which came with your calculator. If you have not got it then if you search the model number in Google, then you will be able to find the manual.
This is quite a common exercise in the exam!
