1.AB+CB=D
B(A+C)=D
B=D/(A+C) ANS.
2.B*B=A
B^2=A
B=SQRTA ANS.
3.AB/C=D
AB=CD
A=CD/B ANS.
4.A/B=C/D
AC=BD
A=BD/C ANS.

1. AB + CB = D

B(A + C) = D

B = D%2F%28A+%2B+C%29


2.B*B=A
B%5E2+=+A
B+=+sqrt%28A%29

3.AB/C=D

AB%2FC++=+D

AB = CD

B++=++CD%2FA

4.A/B=C/D

A%2FB++=++C%2FD

BC = AD

B++=++AD%2FC
