Hello. I hope you can help me. I was just trying to figure out where all the numbers are coming from but I still don’t understand how did they get answer r =0.78?
I get that r4=0.375 and I just cannot figure out the final answer.
at the moment I am assuming that you have this BPP revision kit it is 2019 -2020, if not I will type the whole question. Thank you very much for your help.
r^4 = 0.375
Therefore r is the fourth root of 0.375, which is 0.78.
Have you watched my free lectures on learning curves? The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
Thank you John. I did but I think I will have to do it again. Many thanks for help. I just couldn’t work it out on the calculator….
You should have a button which calculates any root.
If not, then a 4th root is the same as taking the square root twice.
Thank you so much! That really helped me! I couldn’t stop thinking about it for 3 days now! 🙂
