5-127.

One student rewrote the expression $17·102$ as $17(100+2)$, and then simplified to get the expression $1700+34$.

1. Are the three expressions equivalent? Justify your answer.

Do you get the same answer when you evaluate all three expressions?

$17(102)=17(100+2)=1700+34$ Is this true?

2. What property of numbers does this demonstrate?

Do you recall what property allows you to distribute a multiplier of each term in a sum?
