Answer 1

Answer:

Option D.

Step-by-step explanation:

Consider the given expressions are

$14^2\times 12^2\times 12^1$

$14^2\times 12^3$

$14\times 14\times 12\times 12\times 12$

$14^1\times 14^1\times 12^2+12^1$

On solving these expression we get

$14^2\times 12^2\times 12^1=14\times 14\times 12\times 12\times 12=338688$

$14^2\times 12^3=14\times 14\times 12\times 12\times 12=338688$

$14\times 14\times 12\times 12\times 12=338688$

$14^1\times 14^1\times 12^2=14\times 14\times 12\times 12+12=28236$

First three expressions are equivalent and fourth expression is not equivalent to others.

Therefore, the correct option is D.
