Wow really good job 🎉🎉🎉

How about just (8^6 - 1)/(8 - 1) = (262144 - 1)/7 = 262143/7 = 37449. If you can't readily calculate 8^6, then (8^6 - 1)/7 = (8^3 - 1)(8^3 + 1)/7 = (512 - 1)(512 + 1)/7 = (511 × 513)/7 = 513 × (511/7) = 513 × 73 = 37449.

5^5/5 ➖ 2^3^4 1^1/1 ➖ 2^3^2^2 /1^3^1^2 /32 (x ➖ 3x+2).

Superb

Good . . .

Excellent 🎉

Really? That seems really easy

8^5+8^4+8^3+8^2+8^1+8^0=(8-1)(8^5+8^4+8^3+8^2+8^1+8^0)/(8-1)=(8^6-1)/(8-1)=(2^18-1)/7=(2^10x2^8-1)/7=(1024x256-1)/7=(262144-1)/7=37449 from Japan

Только Вы, как 0,1%, можете решить, а остальные НЕТ? Как интересно. Это ВСЁ относиться к заголовку и к тому, кто это написал.

8^8-8^7-8^6 = 8^6* (64-8-1) =( (10-2)^3)^2*5*11 = ((10-2)(100+20+4))^2*5*11 =(100-20+4)(10000+2*24*100+900-360+36)*5*11 =(100+24)*(10000+5700+324)*5*11 =(100+24)(10000+6024)*5*11 =(50000+30120)*(1100+264) =(80120)* (1000+364) =80120000+ 24036000+80120*64 =104156000+480720+320480 =104636720+320480 =104957200 =68200000+

Пифагор жил, живет и будет жить!🤣

अंस=(3^4)^4--(3^2)3=3^16--3^10=3^10(3^6--1)=3^10(243--1)

= 9^8 - 9^5 = 9^5*（9^3-1^3） = 81^2 *9 *（9-1）*（9^2+9+1） = 81^2*72*91 =6561* 819*8 =6561*（1000-181）*8 =（6561000-6561*181）*8 =52488000-6561*181*8 =52488000-（7000-431）*181*8= 52488000+431*1448 -7000*1448

(2^18 - 1)/7 = ((1024^2)/4 - 1)/7 = (1048576/4 - 1)/7 = 262143 / 7 = 37449

Simplify:- (16x16x16x16x16)-(16x16x16x16)=16 simple

The solution proposed looks like something a Harvard Grad would produce. Meanwhile...I just multiplied it out. Took about 30 sec. even without a calculator.

(5555+4444) (5555-4444) = 9999 x 1111 =11108889

16^4(4^4-16)=240*16^4=15728640

Very simple implementation of the identity a^2-b^2 = (a+b)×(a-b) , a childish topic

It is surprising that you are teaching multiplication addition etc . to a student appearing Olympic exam.

This could be done in very short steps. 500.500-400.400.take out 10000 common 5.5-4.4=9 now 9 *10000=90000 ans

9999x1111 = (10000-1)x1111 =11110000-1111 =11108889

Похоже, Вы единственный 0,1% который умный, остальные неучи. Обидно за Вас.

8^6 - 1 Or 2^18 -1

If you understand the fundamental meaning of "squared" this should be an easy calculation. Draw a square with side 500. Then draw another square with side 400 inside this big square starting from one corner. Can you now visually see the difference in area between the two squares? 400*100 + 400*100 + 100*100

Show smart, it is(8^6-1)/7

Easy method: 500² - 400² a² - b² = (a+b)(a-b) (500+400)(500-400) 900(100) 90 000 Not quite as easy method: 500² - 400² (5•10²)² - (4•10²)² 25•10⁴ - 16•10⁴ (25-16)10⁴ (9)10 000 90 000

God! Why not 64.65 = 4160 ?
