Answer 1

Answer:

d) 24xy2 is answer according to me

Answer 2

Option B - $GCF(4xy^2,20x^2y^4)=4xy^2$

Step-by-step explanation:

To find : What is the greatest common factor of $4xy^2$ and $20x^2y^4$?

Solution :

First we factor the terms,

$4xy^2=2\times 2\times x\times y\times y$

$20x^2y^4=2\times 2\times 5\times x\times x\times y\times y\times y\times y$

The greatest common factor is

$GCF(4xy^2,20x^2y^4)=2\times 2\times x\times y\times y$

$GCF(4xy^2,20x^2y^4)=4xy^2$

Therefore, option B is correct.
