What is the square root of 18 written in simplest radical form
1 answer:
To get the simplest radical root form for a non-perfect square, always factor out the number first.
So, for 18, find the factors.
18
6 3
2 3 3
2 3²
so, when you find a pair of the same two numbers, they become squared. Eliminate the squared signs; that number goes to the left, and the left over numbers are multiplied and are put into the square root sign. So, you end up with the final answer:
3

1. Each shelf holds 5 hermit-crab cages. There are 23 hermit crab cages to be displayed. Divide the number of hermit crab cages to be displayed by the number of hermit crab cages that can be displayed on each shelf:
This means that you need 5 shelves (4 shelves is not enough, because 3 hermit crab cages will be not displayed).
2. Each shelf holds 3 hermit-crab care booklets. There are 12 hermit-crab care booklets to be displayed. Divide the number of hermit-crab care booklets to be displayed by the number of hermit-crab care booklets that can be displayed on each shelf:
This means that you need 4 shelves.
Answer: first, you have to divide 23 by 5 and find the quotient and remainder and divide 12 by 3 and find the quotient and remainder. Then you have to determine the number of shelves needed. You need 5 shelves.
Step-by-step explanation:
Divide 140 by to represent the amount of hours he worked.
To make dividing easier, can also represent 2.8 as a decimal.
He has worked 50 hours after completing 140 rows of grapes.
