Hey there i proved 2=0. worth of 50 points and No spamming. Can find the mistake. 2 = 1 + 1 2 = 1 + √(1) 2 = 1 + √(-1 * -1) 2 = 1 + √(-1)√(-1) 2 = 1 + i(i)→→let √(-1) be i [cause it convenient] 2 = 1 + i2 2 = 1 + (-1) 2 = 0 Can you figure it out? The answer hides in 8th standard math book→ a very big clue!
