So that must be right, right?

never ask a group of random people to do math, they will get it wrong 90% of the time

[ExplodingDarth]

It's an easy misunderstanding if you look at it really quickly and think it's asking which number is the square of a number that is also a square number

[coryburris]

"Ask the audience" should be used for a pop culture question, not something that involves math or science

I always try to introduce my students to the legendary 3, 4, 5 triangle

[anujthakur]

As matter of fact, any number is square of some number and is also can be portrayed as sum of squares of two smaller numbers than it, but it's not necessary that it must have a proper integer as a root , it's most likely to be irrational or recurring number after decimal, this is because right angled triangles for three numbers ( Pythagorean triplet) can be formed for recurring numbers as well.

25, easy, because 9+16 = 25, and both of them are square numbers

As an Asian after 14 nanoseconds I had the answer

[janiajain]

I didn't realised that earlier but i saw this video 3 times just to see when sir will solve it .
Just after reading the question i knew rhe answer.
The best method i could think of are simple triangle measure 3, 4 and 5.
2. factorising

[markkimuszer]

This one seems a bit intimidating at first since you might think of a lot of possibilities and since the thought that goes into it is x² + y² = 25 which, while i personally find an easy solution to reach, could easily slip your mind in the heat of the moment

[Beast-ypei]

While 25 is the answer I would pick, all of them work from two methods. Using 0 or using radical answers

[alexisespinoza-desjardins]

I got B right away. Perhaps they didn’t read the question properly, but what are the odds?

[arianu]

the most popular triangle: 3, 4, 5
&
the secont most popular triangle: 6, 8, 10
I can guess he's just not ASIAN🗿👌

I also learnt today that a surprising number of Americans think π=22/7. I'm not sure what the average teachers have over there, but they certainly lack your passion and intellect.

[Raw_Toast_]

The way I did it was to take the square root of all 4 numbers. Whichever one is the 3rd number in a pythagorean triple is the answer

[rufhoerhid]

Me being confused if "two smaller square numbers" meant the number you square (3, 4, 5) or the square number itself (9, 16, 25)

50% of the audience are either black american women or white blonde american women

[tamirerez]

Let's start with a question:
Is there anyone in the audience, from those who said the answer is 16, who can show me two square numbers whose sum is 16??
The answer is: No!!
So why is there someone who said 16 if he can't justify his answer and certainly can't prove it.

And now for the simple solution, at the elementary school level:
For a number to be the sum of two square numbers it must be an hypotenuse of a right triangle. (Pythagoras theorem)
The most basic triangle is 3-4-5 so the hypotenuse should be a multiple of 5.
And only 25 can be the correct answer.

5²=3²+4²

[colinjava]

The frustrating thing is that you can work it out from the question, it tells you they are all square numbers below, so hopefully one can figure out what a square number is.
Then try adding different square numbers, youll find 9+16=25.
With thousands of $ at stake why screw it up?
