22,000/(16 × 3,500) = r4
its learning curve calculation
please can you help me to calculate it on calculator
The answer is 0.79 or 79%
Thanks22,000 / (16 x 3500) = 0.3929
Therefore r is the fourth root of 0.3929
You must have a scientific calculator for Paper F5 and therefore you will have a button to let you take any root.
However because this is the fourth root, you can do it by simply taking the square root twice.
