17. If pº = q = Pand=, then show that p(r-q) = q(p-r).
b = 40 + 7E/50 make E the subject
13. If 22a = 34b = = 5 = 3 30abc, then find the value of ac + 2bc + 4ab.
P(x)=m(x^4)+n(x^3)+1 when x=1 double multiplicity
A∩[(B∩(A∪B))∪(A∪(A∩B))]
calcular m y n, de modo que P(x)=mx^4+nx^3+1 admita la raiz x=1 de multiplicidad doble
