a certain country had a total annual expenditure of $ 9.6 x 10 ^ 11 last year . if the population of the country was 240 million last year , what was the per capita expenditure ?
total expenditure / population = per capita expenditure hence , ( 9,6 x 10 ^ 11 ) / 240 000 000 = ( 9,6 x 10 ^ 11 ) / ( 2,4 x 10 ^ 8 ) = 4 x 10 ^ ( 11 - 8 ) = 4 x 10 ^ 3 = 4000 . answer is e .
divide(multiply(9.6, power(10, 11)), multiply(240, power(10, add(const_4, const_2))))
