Simplify ((q^(3-7)q xx q^(6-2q))/(q^(2q)xx q^(9-2q)))^((1)/(9))

Two large , parallel conducting plates X and Y , kept close to each other , are given Q_(1) and Q_(2) (Q_(1) gt Q_(2)) . The four surfaces of the plates are A,B,C and D , as shown (i) The charge on A is (1)/(2) (Q_(1) + Q_(2)) (ii) The charge on B is (1)/(2) (Q_(1) - Q_(2)) (iii) The charge on C is (1)/(2) (Q_(2) - Q_(1)) (iv) The charge on D is (1)/(2) (Q_(1) + Q_(2))

If (p/q)^(n-1)=(q/p)^(n-3) , then the value of n is

Simplify: (2.5p-1.5q)^(2)-(1.5p-2.5q)^(2)(m^(2)-n^(2)m)^(2)+2m^(3)n^(2)

Let A=[(l,m,n),(p,q,r),(1,1,1)] and B=A^(2) . If (l-m)^(2)+(p-q)^(2)=9, (m-n)^(2)+(q-r)^(2)=16, (n-l)^(2)+(r-p)^(2)=25 , then the value of |det(B)-140| is_______
