i hope it will help u

pls mark me as brainlist and pls follow me

Answer 2

The required "option 2) Associative" law is correct.

Step-by-step explanation:

We have,

16 x 25 = 8 x 2 x 5 x 5

= 8 x 5 x 2 x 5

= 40 x 10

= 400

For any integers a, b and c, we have:

(a × b) × c = a × (b × c)

The given multiplycation follow is associative law for mutiplycation.

Hence, the required "option 2) Associative law" is correct.
