Answer 2

Answer:

7236×9

Explanation:

Given,

7236×56 _ (I)

Correct one

And, 7236×65 _(II)

So, from equation (1) and (II)

We see that If we subtract equation one from equation two, we will get the answer without multiplying 2 times.

7236×65-7236×56

Taking 7236 as common,

7236×(65-56)

7236×9

= 65124.
