what is 20x20x20x20?

What answer do you get?

160,000

That's the same answer that I got. :-)

To find the value of 20x20x20x20, you need to multiply 20 by itself four times. Let's break it down step by step:

Multiply 20 by itself:
20 x 20 = 400

Now, we need to multiply this result by 20:
400 x 20 = 8,000

Multiply 8,000 by 20 once more:
8,000 x 20 = 160,000

Finally, multiply 160,000 by 20 for the last time:
160,000 x 20 = 3,200,000

So, 20x20x20x20 is equal to 3,200,000.
