Answer 2

Given,

The pair of terms are given as follows,

Option A:

$32y,6y$

Now we have to find whether the given terms are unlike terms.

The power of $y$ in $32y$ is equal to $1$

The power of $y$ in $6y$ is equal to $1$

The power of both the terms is same,

Therefore, they are like terms.

Option B:

$3x^{2} y^{2} , 18y^{2} x^{2}$

Now we have to find whether the given terms are unlike terms.

The power of $xy$ in $3x^{2} y^{2}$ is equal to $4$

The power of $xy$ in $18 y^{2}x^{2}$ is equal to $4$

The power of both the terms is same,

Therefore, they are like terms.

Option C:

$13z^{2} x,20xz$

Now we have to find whether the given terms are unlike terms.

The power of $zx$ in $13z^{2}x$ is equal to $3$.

The power of $zx$ in $20zx$ is equal to $2$

.The power of both the terms is different.

Therefore, they are unlike terms.

Option D:

$30xy^{2} ,40y^{2} x$

Now we have to find whether the given terms are unlike terms.

The power of $xy^{2}$ in $30x y^{2}$ is equal to $3$

The power of $xy^{2}$ in $40 y^{2}x$ is equal to $3$

The power of both the terms is same,

Therefore, they are like terms.

Therefore, the option C is correct.
