Sir,
My question is how to use r using scientific calculator.
For example 9000= 16 x 1500 r4
How do I convert it to 78% using scientific calculator?
Thank you sir
Nura
Abuja, Nigeria9,000 = 16 x 1500 r^4
Therefore r^4 = 9,000 / (16 x 1500) = 0.375
Therefore r = 4th root of 0.375 = 0.78
As to how to take the 4th root, different calculators have different buttons – you will need to look in the calculator manual to find out how your calculator does it. (If you have lost the manual then search the model number in Google and you will be able to download it)
In fact, for a 4th root you can just take the square root twice, but this will not help if you end up having to take a 5th root 🙂
