Math Question 0.sqrt(2)

[Wictorian]

Maybe you have seen this meme. It says sqrt(2)/10 = 0.sqrt(2). Is it incorrect?

if that dot means multiply yes it is incorrect

i was finding places where i can put math texts i guess topic is good for me.

anyway,

in 0.sqrt(2),...... no it's wrong bcuz

 

sqrt(2)/10 = 0.1414... ( 1414 is not equal to sqrt(2) )

so

0.sqrt(2) ≠ 0.1414...

 

this 0.sqrt(2) should have been written like this = 0.1* 1.414 = 0.1*sqrt(2)

I am not asking if sqrt(2) is equal to 0.1414 tho. Basically is 0.1*sqrt(2) equal to 0.sqrt(2) ? Some guy was saying it is not because it would be double dots (0.1.1414)

No it does not. Imagine it is a comma. Basically 0.5 means 5/10

Incorrect notation.  It's like writing a command line that isn't in the library for a code language, like writing 0.X.  Simplified, does 1/10 * X = 0.X?  No idea, because X could be indeterminate, and transcendental numbers can do really weird things.  No, scientifically because you're creating a significant figure out of thin air, and mathematically because there's no function to tie together the "independent expressions" in a cohesive way.  The question isn't whether the math is correct, the question is that if the math is written in math in the first place; if it's not than it's not math.  is 0.1sqrt(2) = banana?  No.  is 0.1sqrt(2) = 0.sqrt(2)?  No, the second expression isn't written in the correct notation, just like the example before it.

No it is not.

No it's still wrong.

Correct ones are below

0.1·1.414 or 

0.1*1.414 or

0.1x1.414

You are trying to write in decimal form in this word form it is correct, technically or in form of trick question YES but in number form no it is not!

What do I mean by trick/intelligence test question -

 

[Root(2)]/10 = ?

A) 2

B) 0.root(2)

C) 0.2

D) 20

 

In this case ofcourse B is correct!

But if we leave this context then more correct is and always will be

0.1414 or 0.1*root(2). And so, 0.root(2) will be wrong outside of that context.

 

And no root(2)/10 is not equal to 0.root(2) in math world. Bcuz decimal forms doesn't work that way.

 

What's more correct natural numbers or real numbers in reallife world? Ofcourse answer is Real numbers.

(I would like to emphasize that there are only two options in this question Real or natural so don't go & bringing other numbers).
