Dear sir please.solve question 3b
ax / ay = ax-y
Then, the first term becomes:
a(x-y)( x2 +xy + y2) = a(x3 - y3)
Proceeding like this:
The given expression reduces to,
a(x3 - y3) . a( y3 - z3) . a(z3 - x3) = a( x3-y3+y3-z3+z3-x3) = a0 = 1
Then, the first term becomes:
a(x-y)( x2 +xy + y2) = a(x3 - y3)
