Let A = (2016)²⁰¹⁷

Take log on both sides, we get

      log₁₀ A = log₁₀ (2016)²⁰¹⁷

=> log₁₀ A = 2017 * log₁₀ (2016)

=> log₁₀ A = 2017 * 3.304             {since log (2016) = 3.304 using calculator}

=> log₁₀ A = 6664.168

=> A = 10^6664.168

Without calculator, it is very difficult to calculate.

If the numbers are in power of 10, then it is very easy to calculate without using the

calculator.
