That tangent failed to solve the original problem. There is no method provided for computing the remaining result efficiently without a calculator. No marks.
I don't feel like this is a satisfactory 'answer' to the original problem. 9^900-9^901 simplifies to 9^900(-8). How does rewriting that as -(3^1800)*(2^3) help? I'd argue that -8*9^900 is a simpler form. But arguably 9^900-9^901 isn't that much worse.

But where is the answer for your first question. You need to give a final value without calculator

(199+1)^2-199^2=399

3^2^10^90 ➖ 3^2^10^91 1^1^2^510^90 ➖ 1^12^510^90^1 1^12^5^9^10 ➖ 1^12^5^9^10 1^19^2^5 ➖ 1^19^2^5 3^2^1^1 ➖ 3^2^1^1 1^1 ➖ 1^3 1^3(x ➖ 3x+1). Avery exiting videos.
WTF?
this wastes my time, why explaining simple math formulas instead of giving the answer to the problem you posted? Worst math video ever seen
