Question

What is the value of $2\times 4\times 6\times 8$?

• A. $48$
• B. $64$
• C. $384$
• D. $192$

Answer 1

The correct option is C $384$

To get the final value of $2\times 4\times 6\times 8$, we first multiply $2$ and $4$, and then multiply $6$ with the product of $2$ and $4$.

Hence,
$2\times 4\times 6\times 8$
$=(2\times 4)\times 6\times 8$
$=8\times 6\times 8$
$=(8\times 6)\times 8$
$=\left(48\right)\times 8$
$=(40+8)\times 8$

Now, we use box method to find the value of $(40+8)\times 8$.

	$8$
$40$	$40\times 8$ $=10\times 4\times 8$ $=10\times 32$ $=320$
$8$	$8\times 8$ $=64$

$\therefore (40+8)\times 8=320+64=384$

Hence, the value of $2\times 4\times 6\times 8$ is $384$, i.e., option (c.) is the correct one.
