Answer:
±√3
Explanation:
Given: If b+b+b=b∗b∗b , what is b besides 0?
3b =

Since I'm assuming we disregard b=0 as a solution, we can divide both sides by b
3 =
Now we need to be careful here since b could be positive/negative, when we square root both sides it will be absolute valued
3–√=|b|
So either, b = √3 or b = –√3
