Practice with the properties of real numbers The word NUMBERS implies the answer will deal only with numbers The word X implies the answer will contain a variable, but not necessarily the variable x A B Distributive Property (Numbers) 3 (5 2) = 15 6 Commutative Property of Addition (Numbers) 3 7 = 7 3 #(xy)^3=(xy)(xy)(xy)# Expand the first two brackets #(xy)(xy)=x^2xyxyy^2# #rArr x^2y^22xy# Multiply the result by the last two brackets #(x^2y^22xy)(xy)=x^3x^2yxy^2y^32x^2y2xy^2# #rArr x^3y^33x^2y3xy^2# We know that x3 y3 z3 3xyz = (x y z) (x2 y2 z2 xy yz zx) Putting x y z = 0, x3 y3 z3 3xyz = (0) (x2 y2 z2 xy yz zx) x3 y3 z3 3xyz = 0 x3 y3 z3 = 3xyz Hence proved Show More Ex 25 Ex 25, 1 Ex 25,2 Important Ex 25,3 Important Ex 25,4
