In the formula `k=((a+b)/(a-b))^((1)/(2))`. Rewrite the formula by making 'a' the subject.

In the formula k=((a-b)/(a+b))^(2) , find the value of b if k=36 and a=3, making b the subject.

If the formula y=(a+b)/(a-b) , make a as the subject.

In the formula t_(n)=a(n-1)d , make n as the subject

A is the area of the rectangle with length l units and breadth b units. Rewrite the formula for area making l as the subject.

In the formula s=ut+(1)/(2)at^(2) , make a as the subject of the formula
