what is so special about 1729?

its the smallest no. which can be expressed in more than 1 way as sum of cubes of 2 integers.

12,1 and 10,9

This is the place where i live and it often appears to be mixed up. find the logic to it-

n t d s a e . f a e i a u i e ?

here goes a hint

its really a big place on eart (no puns intended) and it doesn need any computer program, also the answer is of 20+ letters and i have given only 12 13 words, so just try to guess what's missing

Steve owns an antique car, which is on its second engine. The combined age of the car and the engine is 84 years. The car is currently twice as old as the engine was when the car was as old as the engine is now. How old are they now?

very cool puzzle

let car be x yrs old and engine be y,

hence x-y years ago, car's age= y, engine's age=2y-x,

hence x=2(2y-x) and x+y=84,

we get x=48 and y=36

Great puzzle, Dark, I hope to see more from you.

yeah sure.......

Seeing as it's only a linear equation and I've already played a little with it in my head I'll let someone else solve it

it's not a linear equation

By solve I mean, post the answer. I know that won't gain me any reputation, but this is so easy for me I don't want to spoil it for anyone else. That's what I get for being a programmer lol.

your wish no problem, but i was looking for an answer without using a computer program

We can rewrite the equation as: y2+432=x3

so y= 36

and x=12

very well done sir (if u did it not using a program), and yes since we r dealing with y^2, hence x-12, y=12, -12

I was wondering why it looked so like a linear equation

i have this bad habit of not previewing my posts

I've figured out two things it is not.

and what are they?

Thank you, I am starting to enjoy making riddles very much . Once again, another within a week.

KEEP up the good work and congrats solomon

I can growl, roar, and scream,

But no sound do I release,

I can pounce, crawl, and run,

But my realm is restricted,

As defenseless as you,

No matter how dangerous I appear,

I can never make a choice,

But simply follow premade footsteps,

What am I?

i cant think much, but is the answer "our soul"

hey everyone i m really sorry for my carelessness, its y^2=x^3-432, not y2,x3 and all that, i regret for being careless, this wont be repeated in future.

y - x = 72?

umm... nope

Find all integer solutions of y2 = x3 − 432.

Try to solve this without using a computer program

All the best!!

and i agree this is a dumb title i have come up with.

all the way home, then walk the 3 blocks back to the bar.

but wont that make them to walk 3 blocks, just as much as given in question, or may be i just misunderstood u

cant think of a better plan than the one u mention, though there is one which assures same amt of walking, may be got to think out of the box

always use spoilers fro nxt time, good job

134456 because...

If you write the numbers backwards, 19208 2744 392 56 8

then divide the first one by the next one like so..

19208/2744 =7

2744/392 =7

392/56 =7

56/8 =7

Each problem is equal to 7, so that is the pattern.

To find the "?" ...

?/19208 =7

19028 x 7 =134456

vinays84 and carolyn have solved the problem! good job!

gvg......gv

yuiop....yup! (that's how i pronounce it...)

qwerty....qrty!

*Anyone feels they need a nickname? Ask me!!!

pain??

8 65 293 4472 80291 ?

looking back on things, makes this seem perfect

Possibly should have been in math and logic, though?

this riddle belongs to this section only

Does the period separate two words? Nice riddle BTW.

sorry buddy i was busy, u need to figure this on your own

its a place, as the question says
