if 1,000 microns = 1 decimeter, and 1,000, 000,000 angstroms = 1 decimeter, how many angstroms equal 1 micron?
multiply(divide(1, multiply(const_100, const_100)), multiply(const_100, const_100))
"given that 1,000 microns = 1 decimeter = 1,000 , 000,000 angstroms so , 1 micron = 1,000 , 000,000 / 1,000 = 1 , 000,000 answer : c"
