You're wrong because you neglected to specify the base, so the default is base 10, but there's no digit 'F' in base 10. If you had written 0xF0000 or 0F0000h, then it would be acceptable.
This seems to be a lie. As a Harvard graduate, I can say that Harvard didn't ask me any math problems for admission other than the standardized tests such as SATs and APs. Maybe, they did 100 years ago.

I seriously doubt that one was a question on any university admission test, more so at Harvard, and assuming it was, if any of the students would have solved it the way you did, I think he/she wouldn’t make it any further. You may want to learn again the use of parentheses.
Por éso mucha gente odia las matemáticas, por profesores que las complican al momento de explicar. Te extendiste demasiado en algo tan fácil. Para calcular esto, necesitamos seguir el orden de operaciones: 16^5 - 16^4 Primero, calculamos los exponentes: 16^5 = 16 × 16 × 16 × 16 × 16 = 1.048.576 16^4 = 16 × 16 × 16 × 16 = 65.536 Ahora, restamos: 1.048.576 - 65.536 = 983.040 La respuesta es 983.040.
16^5 - 16^4 = 16^4 * 15 = 16 * 16 * 16 *16 *15 = ... . and this is calculation for 4th grade Kids 😂 but not Harvard Let the 4th grader help and it will be faster
Thank you.
some alternate method:
16^5 - 16^4
= 16^4 * 16 - 16^4
= 16^4 (16-1)
= (2^4)^4*15
= 2^16 * 15
= 983,040
Almost the same method😊
This solution makes much more sense.
UR RIGHT HIS SOLUTION SILLY
日本の中学校卒業レベルならば、この方法をとると思います。難しく考える必要はないです。
You make so complicated..you can take 16^4 out so inside you will get 16 -1 = 15.. 16 ^3 × 16 x15 = 16^3 × 240 = 4096 ×240 = 4096 × (250 -10 ) = 1024000 -40960 = 983040
The simpel problem that you make complicated
Let me solve this step by step:
First, let's factor out 16^4 from the expression
16^5 - 16^4 = 16^4(16^1 - 1)
16^4 = 16 × 16 × 16 × 16 = 65,536
16^1 - 1 = 16 - 1 = 15
Therefore:
16^5 - 16^4 = 65,536 × 15 = 983,040
The answer is 983,040
I worked it the same way. Much simpler!!!!
Let 16^4 = p
16p - p = 15p
But, 16^4= p (from above)
Hence, 15 * 16^4 = 😁😁😁😁
16^5-16^4=?
16^4x16-16^4=16^4x(16-1)=16^4x15=16x16x16x16x15=983,040
很簡單,何須兜圈子 ?
