Question 4. Asked on :09 January 2019:09:37:10 AM

 Ques.1. prove that 2+2= 5

Answer:

Nishant Verma

Start with: -20 = -20

Which is the same as: 16-36 = 25-45
Which can also be expressed as: (2+2) 2 (9 X (2+2) = 52) 9 X 5
Add 81/4 to both sides: (2+2) 2 (9 X (2+2) + 81/4 = 52) 9 X 5 + 81/4
Rearrange the terms: ({2+2}) 9/2) 2 = (5-9/2) 2
Ergo: 2+2 - 9/2 = 5
Hence: 2 + 2 = 5

Answer:

khushi chauhan

 0 = 0

=>4–4 = 10 - 10

=>2²-2² = 2x5 - 2x5

=>(2 - 2)(2 + 2) = 5(2 - 2)

Cancelling (2–2) from both sides we get

2+2 = 5

Proved.

But this is totally wrong, I guess even you know that we can't cancel (2–2) from both sides.

Now the real proof

2+2 = 5

It's true only if:

Answer:

Akki chauhan

 Let,

         22-22 = 10-10

Identity,

             a2-b2=(a+b) (a-b)

            (2+2) (2-2)=5(2-2)

Now,   (2+2)=5(2-2)÷(2-2)

           2+2=5    (Prooved)

Question 5. Asked on :09 January 2019:09:36:20 AM

What is Euclid's division algorithm. 

-Added by Master Purushottam See More Answers Mathematics » Number System

Answer:

Nishant Verma
The basis of the Euclidean division algorithm isEuclid's division lemma. To calculate the Highest Common Factor (HCF) of two positive integers a and b we use Euclid's division algorithm. HCF is the largest number which exactly divides two or more positive integers.
