## Text Solution

 S.No. Expression Terms Factors Like/ Unlike Reason (i) $$1, 100$$ $$1$$ and $$100$$ $$1$$ and $$100$$ Like Bothe the terms has no variables (ii) $$–7x, x$$ $$–7x$$ and $$x$$ $$–7, x$$ and $$x$$ Like Both terms have same variable $$x$$ (iii) $$– 29x, – 29y$$ $$– 29x$$ and $$– 29y$$ $$– 29, x$$ and $$– 29, y$$ Unlike Both terms have different variables $$x$$ & $$y$$ (iv) $$14xy, 42yx$$ $$14xy$$ and $$42yx$$ $$14, x,y$$ and $$42, y,x$$ Like Both terms have same variable $$xy$$ & $$xy$$ (v) $$4m^2p, 4mp^2$$ $$4m^2p$$ and $$4mp^2$$ $$4, m^2, p$$ and $$4, m, p^2$$ Unlike Both terms have same variable but with different powers (vi) $$12xz, 12x^2z^2$$ $$12xz$$ and $$12x^2z^2$$ $$12, x ,z$$ and $$12,x^2 ,z^2$$ Unlike Both terms have same variable but with different powers
