**Question 14:**

(a) Find the

**of 3375 and write your answer in***prime factorisation***.***index notation*(b)

*Hence, deduce and write down*(i) the smallest 2-digit number that is a factor of 3375

(ii) the largest 2 digit number that is a factor of 3375

(iii) the smallest 3-digit number that is a factor of 3375

(iv) the smallest 4-digit number that is a factor of 3375

For Prime factorisation of 3375, why choose 3 to start with? How did you choose those numbers?

ReplyDeleteIshani keep kick her leg

ReplyDeleteWS put his hands into the pocket

NO eye contact

Talking to wall

The ladder to find the prime ladder... why use one no at a time instead of both together?

ReplyDeletewei siew put his hands into his pocket at the start, and Ishani was swinging for the whole time that she was speaking, and they did not explain the question before plunging into saying all the working which is as good as just letting us look at the paper.

ReplyDeleteI don't really understand what they are talking about

ReplyDeleteQuite soft.Only reading from the paper and not giving proper explanations.Many stammering.Don't understand what is the questions what more the answers.

ReplyDeleteFYI, im Lovy

They are not explaining, simply reading off the paper....

ReplyDeletewrong wrong.. take out my 1st comment

ReplyDeleteWhy must you use 5 for the third "bar" of the ladder instead of 3?

They are speaking a bit too fast ,soft , and monotonous.

ReplyDeleteNo eye contact.

Ishani keep kicking her leg.

WS's body language is poor .

Not systematic.

We can't see the paper .

The solution is abit messy.

We can hear them but don't really understand their solution.

MacSpicy :D

I mean swinging her leg

ReplyDeleteFor the Prime Factorisation of 3375 when you say put the number in index notation, why did you start with 3 and not 5? Also how did you use those answers to deduce down to the smallest 2-digit number factor, largest 2- digit number, smallest 3 digit factor etc.

ReplyDeletePlease respond

They were talking too softly and they were facing the wall, so I could not hear or understand what they were saying and their explanations.

ReplyDeletethe explanantion is not so clear.

ReplyDelete@ms loh, we chose 3 because we should always start with smallest prime number ,2,is the smallest but 3375 is not divisible by so we chose 3 as it was the next smallest number that is able to divide 3375.-ze specs

ReplyDeleteHow did you find the smallest 2-digit number that is a factor of 3375?,

ReplyDeletethe largest 2 digit number that is a factor of 3375?

the smallest 3-digit number that is a factor of 3375?

the smallest 4-digit number that is a factor of 3375?

Can you explain again?

BTW, Nemo is owen.

ReplyDeleteThey did not state what they are finding on the paper. The presenting of the questions is kind of confusing .

ReplyDeleteThe second explanation is clear .

ReplyDeleteMacSpicy :D

@Mark, Yide, Lovy, toby,Ryan.

ReplyDeleteSorry,Why didn't u ask us when ishani asked the audience for questions? We could have explained.

I put my hands in my pockets because cold and I do not know what they writing so just read.
