how can we show that 3is equal to 4?

Answer 1

Here is a (false) proof that 3 = 4. If 3 were really equal to 4, the entire mathematical foundation would crumble and centuries of math would be obliterated.

Let x = 1 and y = 1. It is clear that

x = y. Multiplying x to both sides, we get

x^2 = xy. Subtracting y^2 to both sides, we have

x^2 - y^2 = xy - y^2. Factoring both sides,

(x - y)(x + y) = y(x - y). Dividing both sides by (x - y), we have

x + y = y. Adding 2 to both sides,

x + y + 2 = y + 2. Substituting in back x = 1 and y = 1

1 + 1 + 2 = 1 + 2
4 = 3

Answer 2

well its not just 3 & 4, you can prove any 2 numbers to be equal by violating some laws. replace the numbers you want to be equal by examining the following.

say you want to prove 3 = 4

(3 + 4 )x(3 - 4) = 7 x (3 - 4)
3x3 + 4x3 - 3x4 - 4x4 = 7x3 - 7x4
3x3 + 3x4 - 7x3 = 4x3 + 4x4 - 4x7
3 ( 3 + 4 -7 ) = 4 ( 3 + 4 -7 )

cut off ( 3 + 4 - 7 ) on both sides

so now

3 = 4

you can actually do this with any two numbers :)

try substitutin 3,4 & 7 with respective numbers for an example .

say U want to prove 2 = 6
then replace 3 with 2
4 with 6
and 7 with 8

hope you understand :)
Enjoy


P.S = the trick is you cant cut the phrase ( 3 + 4 - 7 ) as it is 0 (zero) lol!!!

Answer 3

3=4 is almost impossible. Unless you take 3 people, 2 males and 1 female. Have them engage in intercourse and produce 1. Thus you would have 3=4. Or aside from reproduction use an algebraic equation, where you solve for an unknown. 3?=4 Now you must solve for the unknown.

Answer 4

yes i'll show you.

0^3=0^4
=>since bases are equal ,even the exponents should be equal.
since base 0=0. .there fore3=4.
thus actually talking is not right ,but a simple trick to solve this problem.got it!

Answer 5

12/3 =4

12 divided by 3= 4

Answer 6

It is possible if you use algebra.

You can show this by using this expression.

3x = 4y

Where x and y are unknown factors.

So, x = 4y/3 , and y = 3x/4

If x = 1, then you get

3 = 4y

So, y = 3/4

If y = 1, then you get

3x = 4

So, x= 4/3 or 1.1/3 (one and one-third).

Answer 7

I think it is important to stress that "trick" in the proof is dividing by (x-y) which is equal to 0.

Answer 8

By violating the laws of nature and/or mathematics.

Answer 9

Highly convoluted algebra could'nt solve that one for you, sorry!!

Answer 10

by changing the mathematics rules :|
