I think you have some confusion here. Consider this 2^3 - 2^2 Now, according to the doubt you presented it should be equal to 2^1 Let’s check. 2^3 - 2^2 8 - 4 4 Which is not equal to 2^1 or 2 So, to finish it off, the exponent numbers do not work with normal laws of arithmetic. Here are the actual laws: a^m•a^n = a^(m+n) (• in simple language means multiplication of numeric terms) a^m•b^m= (ab)^m a^m/a^n=a^(m-n) I hope you understood. And do not feel bad, it is completely okay to have doubts and confusion. Having doubts means that you are ready to learn.
I think that we can change
9 ^6 to 81 ^3 and
8 to 2 ^3
now the answer is (81*2)^3
= 162^3
which we can calculate in like 3-4 mins at max
My only suggestion is that the sequence from 2:20 thru 3:40 is just undoing previous steps.
162^3?
Are you getting paid more money if the vid is longer?
{0+0 ➖} ^1=1^1 (x ➖ 1x+1).
9^7 - 9^6 = 9^1?
r u serious
You have singlehandedly made me jump off my window from 10th floor

2^3 - 2^2
8 - 4
4
Which is not equal to 2^1 or 2

^ means by the power of, not times. Also, 9^7 ÷ 9^6 = 9^1
Seems like you're mistaken in one of these 2 ways.
That only works for division.
