Much quicker and easier to just treat 5^11 as 5^4 x 5^4 x 5^3, which is 625 x 625 x 125. Multiply 625 x 625 and then multiply that product by 125. Then subtract 9. This is much faster than the method shown.

After puzzling over this, the simplest solution seemed to me to be E = ((5^5)^2)*5 - 9; 5^5=3,125; so by long multiplication 3,125*3,125 = 9,765,625 then 9,765,625 * 5 = 48,828,125, and finally 48,828,125 - 9 = 48,828,116; or written out using segmentation and group multiplication, 3,125 * 3,125 = 3,000 * 3,125 + 100 * 3,125 + 20 *3,125 + 5 * 3,125 =9,765,625

As others have said, there are several fairly direct calculations of 5^11 that are probably easier. I choose to use 5^11 = 5 * (5^5)^2 = 10 * (3125*3125)/2. The only non trivial steps in this calculation are a single 4 digit x 4 digit long multiplication and a divide by 2.

This is one of those contrived special-case problems that gives math instruction a bad name. It isn't even one of those convoluted methods that was developed to do arithmetic in the days before computers -- it's easy enough to multiply out by hand (if anyone remembers how to do that). It's a pointless puzzle problem that has no place in a math curriculum.

Just go 5^3=125 then x5 = 625. then x5 again and again until you get 5^11, then don't forget to subtract the 9. THE POINT IS, on some important exam like this there is 1st = time, and this is faster; then as any chess player will tell you, 2=thinking is hard work so go with the simple operation

Using a similar-ish method we can tackle this puzzle: what is 2^5 ? [NO CALCULATORS ALLOWED] 2^5 = (10-8)^5 = 10^5 - 5*10^4*8 + 10*10^3*8^2 - 10*10^2*8^3 + 5*10*8^4 - 8^5 = 100000 - 400000 + 640000 - 512000 + 204800 - 8^5 = 32800 - (2^5)^3 Now (and this is the clever part) setting x = 2^5, we get x = 32800 - x^3. Or x^3 + x - 32800 = 0. So we have reduced our original puzzle to a simple cubic equation!

5^11 - 3^2 = 5^5 * 5^6 - 9 5^5 = 5^4 * 5 = 625 * 5 = 3,125 5^6 = 5^5 * 5 = 3125 * 5 = 15,625 3125 * 15,625 - 9 = 48,828,125 - 9 = 48,828,116 ... ok, might need a pencil to do this multiply

I guess that professors in mathematics from Stanford University, learned at secondary school already in "calculator era". So, they probably do not know about multiplication in column method.

@@superacademy247 Excuse me, if multiplication in column works here faster, let say, it is not the best example of the problem. Should be common sense anyway. And, by the way, how did you get 5^5 so quickly?

Calculations were not allowed. This was hardly a simplification of your calculations, which were inevitabls despite the stupid prohibition. It would have been much simpler to calculate 5 to the 11th and add 9.

I would like to see some proof that this question, and others like it, were actually posed by reputable bodies. They just don't have the right 'vibe', and look as though they have been invented purely for sites like this one. Academics might well ask, "how would you solve this?". But as soon as one mentioned surds, they would move on to something else and not expect lots of tedious manipulation. Academia ranks insight far above kindergarten arithmetic.

As 5^{11} -3^2 is not large, why not compute directly 5^{11} - 3^2 = 125^3 x 25 - 9 = 15625 x 25 - 9 = 1562500/4 - 9 = 390625-9 = 390616
