IT IS POSSIBLE BY ADDING ONE TO 64 OR SUBTRACTING 1 FROM 65

Let us suppose
a=b=1
so v can write
a^2=ab (as a^2 and ab is equal to 1)
Now subtract b^2 on both sides
So the equation will be
a^2-b^2=ab-b^2
As v all know a^2-b^2=(a+b )(a-b)
So using this formula ,we get
(a+b) (a-b)=ab-b^2
=> (a+b)(a-b)=b(a-b)
Now (a-b) is cancelled from both sides or v can say divide(a-b) on both sides
The equation will be as follows
=> (a+b)=b
as a=1 , b=1
So
1+1=1
2=1
Add 63 on both sides
63+2=63+1
=> 65= 64
Hence proved
a=b=1
so v can write
a^2=ab (as a^2 and ab is equal to 1)
Now subtract b^2 on both sides
So the equation will be
a^2-b^2=ab-b^2
As v all know a^2-b^2=(a+b )(a-b)
So using this formula ,we get
(a+b) (a-b)=ab-b^2
=> (a+b)(a-b)=b(a-b)
Now (a-b) is cancelled from both sides or v can say divide(a-b) on both sides
The equation will be as follows
=> (a+b)=b
as a=1 , b=1
So
1+1=1
2=1
Add 63 on both sides
63+2=63+1
=> 65= 64
Hence proved

yeh wohi 'mathemetician' hai naa jiss nay 'mathemetically proove' kia tha k oskay betay ki omer oss (baap) say baRhti jarahi hai.

* bhala woh kaisay
jab woh paida howa thaa:
to maiN 20 saal ka thaa goya maiN oss say 20 times bara tha.
jab woh 5 years ka tha:
to maiN 25 years ka thaa yani oss say 5 times bara tha
jab woh 10 years ka tha:

jab woh 20 years ka hai:
to maiN 40 years ka thaa goya oss say sirf 2 times bara tha.
aaj woh 40 saal ka hai;
aur maiN 60 saal kaa, goya oss say sirf 1.5 times bara houN
saaf nazar aa.raha hai k main age maiN gradually oss say choTa hota jaraha houN... aur woh waqt door nahi jab woh mujh say bara aur maiN chota hojawouNga.
mathemetics say to hum bahoot kuch proove karsaktay haiN jaisay:
(say) taj mahal ko 1000 labourers nay 5 years maiN tameer kia thaa.
5 years = 5 x 365 = 1825 days
1000 labourers build taj mahal in 1825 days
1000 x 1825 = 18,25,000 labourers will build taj mahal in ONE DAY.

iss mai garbaar mere khayal sa divide by (a-b), because a and b are equal so a-b=o and u cannot divide a number by zero. its my understanding of this problem

yes,,, i think,,, thats what he said,,,, that if u have supposed a=b,,, then dividing by a-b i.e., 0 will lead to infinity
