(i) $1,100$
(ii) $-7x,\frac{5}{2}x$
(iii) $–29x,-29y$
(iv) $14xy,42yx$
(v) $4m^{2}p,4m{p}^2$
(vi) $12xz,12x^2{z}^2$

Answer 1

$\begin{array}{ccc}\text{S.NO}& \text{Pair of terms}& \text{Like}/\text{Unlike terms}\\ \left(i\right)& 1,100& \text{Like terms}\\ \left(ii\right)& -7x,\frac{5x}{2}& \text{Like terms}\\ \left(iii\right)& -29x,-29y& \text{Unlike terms}\\ \left(iv\right)& 14xy,42yx& \text{Like terms}\\ \left(v\right)& 4m^{2}p,4m{p}^2& \text{Unlike terms}\\ \left(vi\right)& 12xz,12x^2{z}^2& \text{Unlike terms}\end{array}$
