Why not ? √-1 x √ -1 = √ -1 x -1 = √ 1 and = 1

Wrong...in the 2nd step

@@Avikedu √2 x √ 3 = √ 2x 3 right then √-1 x √-1 = √-1 x -1 it's also the same ... I'm right ?

[@Avikedu]

@@logeshacc no , in case of postive number you can write √1 × √1 = √1×1 but in case of negative number you can't write √-1 × √-1 = √-1×-1 because √-1 = i (iota - imaginary number)
