rounded to 3 decimal places , 1.003 ^ 4 =
as compared to 1 , 0.003 is a very small quantity . thus , we can write ( 1 + 0.003 ) ^ 4 is nearly equal to ( 1 + 4 * 0.003 ) = 1.012 . as the question asks for approximation to three decimal places , the further terms will anyways not come into picture . d .
add(1.003, multiply(divide(3, const_1000), 3))
