must prove!!!!!

#

Uh 4 is not equal to 5🤓

ember ruin
#

By contradiction your statement isn't true

slate sigil
#

lets try to prove why 4 is not equal to 5

Can you prove that thou-

#

Prove that 5-4>0

slate sigil
#

Let 5=4+k

jagged phoenix
#

i mean if you define a = b always beingtrue for any a and b then yeah

next whale
#

0=0
20-20=25-25
4(5-5)=5(5-5)
4=5

#

assuming 0=1

the answer must be a troll

#

I know

#

But that's the answer they expected though

#

I think

#

If 1/3 *3 =1 why is 0.3333333( reoccurring)*3 = 1 not 0.9999999999(reoccurring)

https://en.wikipedia.org/wiki/0.999...

0.999...

In mathematics, 0.999... (also written as 0.9, 0..9, or 0.(9)) denotes the smallest number greater than every number in the sequence (0.9, 0.99, 0.999, ...). It can be proved that this number is 1; that is,

    0.999...
    =
    1.
  

{\displaystyle 0.999...=1.}

Despite common misconceptions, 0.999....

#

No exactly

#

0.9 recurring is exactly equal to 1

#

One way to think about it is if that two real numbers are not equal to each other

#

There will be at least one number between them

#

Eg.
4 and 5 are not equal as there are numbers between them (4.1,4.2729,4.7 etc.)

#

But try doing the same thing for 0.9(recurring) and 1

#

Okay

#

That makes sense

#

The proof is something like

#

If you take the sum from -1 to n of 9*10^n

#

As n approaches -infinity

#

The sum approaches 1

#

Whats much more fun is that ...999.0 = -1

#

1+2+3+4+5....= -1/12 typo things

#

Its a nice symmetry though isnt it?

#

0.999... = 1
...999.0 = -1

that's not symmetrical to me

#

use $\frac{a}{1-r}$ where $a$ is the first term of the sequence and $r$ is the common ratio

#

All 9s on the left is -1 and all on the right is 1

#

And 1 and -1 are symmetrical from 0 on the number line cuz they have the same absolute value

Answer.

I didnt say you cannot make rules sooo

PLUS ONE RHS RULE!!!!

#

4=4+1

#

4=5

slate sigil
river basalt
#

we are learning that right now

#

maths (omg)

#

well not maths prob geograpgy but okay

#

$\sum_{n=-1}^{\infty}9\left(\frac{10}{100}\right)^n$

4/0=5

#

or 4 = 5
multiply both sides with 0
4 * 0 = 5 * 0
0 = 0

#

you’re supposed to prove that 4=5, not use that fact and verify it

4=5 because of the reflexive property of equality. I can use that here because 4=5. 4=5 because of the reflexive property of equality. I can use that here because 4=5. 4=5 because of the reflexive property of equality. I can use that here because 4=5. 4=5 because...

4=5 because 5=4. 5=4 because 4=5. 4=5 because 5=4. 5=4 because 4=5. 4=5 because 5=4. 5=4 because 4=5. 4=5 because 5=4. 5=4 because 4=5. 4=5 because..

huh

#

I can prove that 4=5 in some way buts it not true basically abuse of algebra

#

Let's say a=b

#

Or a2=b2

#

Or a2-b2=0

#

a-b(a+b)=0

#

A=-b

#

Apply two different numbers

#

1=-1

#

2=0

#

2+4=4
