Other way factor f^2 multiple times: Step 1: 7^2(7^3 +7^2 + 7+ 1) + 7 Step 2: 7^2(7^2(7 + 1) + 8) + 7 Step 3: 49(49*8 + 8) + 7 Now its clear that content of the bracket reduce to 50 x 8, therefore the final calculation is 49 * ( 400 ) + 1 = 19607

Seems like an awful long way to get the answer

This is a question of GP in which a=7,r=7,n=5so Sn=a(r^n-1) ________ r-1

S5=7(7^5-1)/(7-1) !!! 😮😁🤣

Super

Ошибка, когда выводила за скобки 50 , проще было бы 7 возвести в пятнадцатую степень на калькуляторе 😃

I just type it into Matlab Symbolic. I can get a symbolic or numeric answers without hurting my brain.

👍👍👍😁🤪👋

Тут обычная геометрическая прогрессия. Школьник 6 класса решит.

7 to the power of 15

Be careful + operant not * between the 7 powers.

No !

This can be more easier 49 x 50 x 8 = 49 x 50 x 2 x 4 = 49 x 100 x 4 = 196 x 100 = 19600

Faster just to calculate

Are you crazy?? (7^6-1)/6

Super simple 11111(base 7) 😅

People in the comments section seems to not understand this video, they say they can solve it much faster with a calculator. The things is, this video teach us how to solve a question like this, because a normal person don't know the value of 7⁸ and plus.

Lack of basic understanding of tables

19607 по формуле суммы членов геометрической прогрессии.

There would be a better and easier way...

У меня получилось намного быстрее - просто я не решал этот бессмысленный пример, неимеющий никакого практического смысла
