Can you equate 3 and 2 by some mathematics logic?
See this illustration:
6 = 6
915 = 410
adding 25/4 to both sides:
915+25/4 = 410+25/4
Changing the order
9+25/415 = 4+25/410
(this is just like a square + b square  two a b = (ab)square.)
Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.
So it can be expressed as follows:
(35/2)(35/2) = (25/2)(25/2)
Taking positive square root on both sides:
3  5/2 = 2  5/2
3 = 2

Two more fun stuffs with Maths... Continued from previous post
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321
And one more
9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
987654321 x 9  1 = 8888888888
9876543210 x 9  2 = 88888888888

Violation of math law is impossible.....We cannot take square root in this case. As square has two values.....we must choose that value which satisfies math las.

Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.
So it can be expressed as follows:
(35/2)(35/2) = (25/2)(25/2)
Taking positive square root on both sides:
3  5/2 = 2  5/2
3 = 2

there is some error from
Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S.
So it can be expressed as follows:
(35/2)(35/2) = (25/2)(25/2)
Taking positive square root on both sides:
3  5/2 = 2  5/2
3 = 2

Take a LCM it is all wrong! dont try be Ptolomey

Hey but you can do like this
12 = 12
921= 1628
3^{2}2x3x7/2= 4^{2}2x4x7/2
adding 7/2 square on both side
3^{2}2x3x7/2 + 7/2^{2} = 4^{2}2x4x7/2 + 7/2^{2}
now look the equation goes like this
a22ab+ b2 = a22ab + b2
now,
(37/2)^{2} = (47/2)^{2}
now, square root on both side
(37/2) = (47/2)
now we can say that
3=4

Impossible. Violation of math law is impossible. Every square root has two solutions. So, you must take the value that satisfies math rule. Don't try to be over smart. This trick work only for primary level students.
