The computer takes 12.19512.... nanoseconds to perform one calculation.
Step-by-step explanation
The computer performs 8.2× 10⁷ calculations per second.
We know that, 1 second = 10⁹ nanoseconds.
Suppose, the computer takes
nanoseconds to perform one calculation.
So, the time taken to perform 8.2× 10⁷ calculations
nanoseconds.
Thus the equation will be............
![t(8.2*10^7)=10^9\\ \\ t= (10^9)/(8.2*10^7)= 12.19512......](https://img.qammunity.org/2019/formulas/mathematics/college/9eoeqrmsd3npvdbxvoi7goyt5j175eod49.png)
So, the computer takes 12.19512.... nanoseconds to perform one calculation.
