therefore

Don't know b properly sowwie

Okays, after diinnnneerrr tiiime I shall do this one
Ok

Not going to decode that
You should - or look at it on a comp. It's beautiful

How would you work out the co-ordinates of y = 5 ^ (x - 1) ?
What do you mean, co-ordinates. As a graph it looks like this.

...It's beautiful
That was from my solution

I'll admit to pikeying the LaTex
5. I've just read about the IMO, and looked at some questions and didn't understand anything then looked at the step by step answers but still didn't comprehend anything, it looks really hard What maths background is required to answer IMO questions other than being a genius?

It's meant to be hard, these are for the top 18 year olds on the planet. But presumably these kids have become adept to problem solving and the style of examination from a very young age.

I know it's meant to be hard but I actually didn't even understand what was going on in the answers. Like what skills are required?

In fairness, much of the IMO content is number theory and geometry, which aren't really covered in schools

Again, I'm sure the solution draws on a lot of niche knowledge and techniques that most people on TSR aren't aware of. If you really want to prep for it, there are a lot of books to prep for the IMO so I would've thought that would be your best bet.

Of course not, I'm not nearly qualified enough to even think about preparing for such competitions. But, I read some just to get a glimpse of how it's like.

Lets go for something a bit different.
Show that:
Woah, never seen anything like this haha I shall attempt it though

It's not as bad as it looks

It's worth pointing out that most IMO candidates receive intensive training for it - it's not just a difference in raw mathematical ability. I would be interested in seeing statistics comparing how IMO students and non-IMO students at top universities perform, to see how large this gap is when the IMO students are no longer performing on a stage that they've been so thoroughly prepared for.

Do you know any particular book about number theory? Sorry if this is out of context.

It looks too beautiful, I don't want to rearrange it
This is just simplifying right? or do I need to use something like logs? :s

I would've thought the level of problem solving they learn from the IMO is transferable...I've heard BMO2's harder than STEP ...

No logs

I would like to find out. Even though my country doesn't have an IMO team.

I imagine he means coordinates of intersection or inflection?

There are no points of inflection:

and nothing to intersect with
