Dunno, never watched it.
Im sure they allow it in school though given its in Maths class!
It is impossible to get to 29 using they numbers without using using powers.

To get a cube, you would have to have the same number 3 times.
And no, on Countdown, you can ONLY use the numbers given - no roots or powers.

Davie,
But to do a multiplication, you need to use the same number multiple times.
Thats what a multiplication is, the same number added together a set amount of times.
The 3 I have used for the cubing action is included in the allowable numbers.

Ok, it this basic. On countdown, you can use +, -, X & /
That's it.
No roots, powers or anything like that.

But in school you can.
My answer is right.

So, you can't.

DC,
Countdown style does not mean "the exact rules of countdown".
Unless of course you think the teacher was also expecting each student to spend no longer than 30 seconds thinking around the questions either, since the rules of countdown say specifically that you only have 30 seconds to answer.
You can get to the number 29, using only the numbers 3, 5, 6 & 9 only once each.

So can i
5-3 = 2
2 next to 9 = 29
So, if there are no rules, you can make it up anyway you like.

Put it this way DC,
My answer might not be acceptable in a televised countdown final, but it sure as hell would get pass marks as an 11 year old's homework.
Your
5-3 = 2
2 next to 9 = 29
Would probably get you placed in the special needs class.
