expr1 = 1 - (1 - x)^2 (1 - y)^3;
expr2 = ToString[expr1 /. (1 - z_)^n_ :>
(StringJoin @@
Table["(" <> ToString[1 - z] <> ")", {n}])]
"1 - (1 - x)(1 - x) (1 - y)(1 - y)(1 - y)"
expr1 == (expr2 // ToExpression)
True

Hi Mathematica Community,
How can I convert the expression:
1- (1-x)=B2 (1-y)=B3
to the expression:
1- (1-x)(1-x) (1-y)(1-y)(1-y)
Thank you
