the ratio of 2 numbers is 10 : 20 and their h . c . f . is 100 . their l . c . m . is ?
"let the numbers be 10 x and 20 x their h . c . f . = 100 so the numbers are 10 * 100 , 20 * 100 = 1000 , 2000 l . c . m = 2000 answer is e"
sqrt(divide(100, add(power(20, 10), add(power(2, 10), power(10, 10)))))
