Answer:
under 7 is 35 and the next box is 9 on top and 45 on the bottom
Step-by-step explanation:
you have to multipy the books Jillian read by how many times 3 can go into 15, which is 5 times. You can also divide 15 by 3 to find out if its multiplied by 5.
√a can be written as (a)^(1/2)
∛a can be written as (a)^(1/3) and so on,
so √15=(15)^(1/2)
