The question says that the divisor of 10^99 should be a multiple of 10^96 which means that the divisor must be divisible by 10^96 , but in the link mentioned above ,in the first answer it says that for the number to be a multiple of 10^96 we need to take numbers from 2^96 , I just took an example , like 2^4 =16 and 10^4 =10000, Now here 10^4 is a multiple of 2^4 ,not the other way round , since 2^4 divides 10^4 ,so then how can 10^96 divide 2^96 ?
