Why did we pick 8 and 6 instead of 4 and 12 since they both multiply to 48?

• because 12 is too big

• because 4 is too small

• because neither 4 nor 12 is a perfect cube so they can't be simplified

• because both 4 and 12 are perfect cubes and too much can be simplified

Why did we circle 2 y's but when we wrote it outside the radical only wrote 1 y?

• we forgot to write one of the y's

• because y*y = y
