Write the formula to calculate Human development index (HDI).

Human development index (HDI) is calculated using three indicators; (Numerical Example)

1. Life Expectancy Index
   \(\frac{Given\;Country's\;Life\;Expec\tan cy\;-\;Minimum\;Life\;Expec\tan cy}{World's\;highest\;Life\;Expec\tan cy\;-\;Minimum\;Life\;Expeca\tan cy}\;\)
   
   
   
2. Education Index
   \(\frac{{\displaystyle\frac{Given\;Country's\;Mean\;Schooling\;Year}{15}}+{\displaystyle\frac{Given\;Country's\;Expected\;Schooling\;Year}{18}}}2\)
   
   
   
3. Income Index
   \(\frac{\ln\left(Given\;Country's\;Per\;Capita\;Income\right)\;-\;\ln\left(World's\;Lowest\;Per\;Capita\;Income\right)}{\ln\left(World's\;Highest\;Per\;Capita\;Income\right)\;-\;\ln\left(World's\;Lowest\;Per\;Capita\;Income\right)}\)
   
   
   
4. Human Development Index (HDI) = ?
   \(Human\;Development\;Index\;(HDI)=\sqrt[3]{Indicator(a)\times Indicator(b)\times Indicator(c)}\)
