In the formula, `x=(p+5q)/(sqrt(3)+2q)`, make q the subject.

In the formula S=sqrt((p^(2)+q)/(p-q)) make q the subject.

In the formula p^(4)-q^(3)=r^(2)-s , make p as the subject of the formula.

If x^(p^q)=(x^sqrt(p))^(q) find p in terms of q

If p=(sqrt5-sqrt3)/(sqrt5+sqrt3), q=(sqrt5+sqrt3)/(sqrt5-sqrt3) , find the value of (p^2-pq+q^2)/(p^2+pq+q^2)

If sectheta =sqrt(p^2+q^2)/q , then the value of (p sintheta-q costheta)/(p sintheta+q costheta) .
