20×10 cubed=2,000 true or false

Well, your question can be read and understood in two different ways,
depending where the parentheses are supposed to be.

Here are the questions and answers for both ways:

Way #1:    (20) x (10)³

(10)³ = 1,000

20 x 1,000 = 20,000

That's not 2,000 so the equation is false.



Way #2:    (20 x 10)³

20 x 10 = 200

(200)³ = 8,000,000

That's not 2,000 either so the equation is false again.
