The product of a number and twice that number is 180,000. What is the multiplication equation?

600 x 300 = 180,000

2n² = 180,000

Step-by-step explanation:

let the number be n

"twice that number" : 2n

"the product of a number and twice that number" : n x 2n = 2n²

"the product of a number and twice that number is 180,000":

2n² = 180,000 (answer)
