Answer:
- you could use a calculator
- If you do not have a calculator you could do a factor tree
- When a number is perfect square then the number that is x^2 is the square root
Explanation:
When doing a factor tree you have to remember that it only works when you have a perfect square as a factor.
ex 1. square root of 180
now you find the biggest number that is a perfect square (ex. 4,9,16,25,36,49,64,81,100...)
36 is the biggest perfect square that goes into 180
180 / 36 = 5
now the 36 is actually √36 so you have to square root it
square root of 36 is 6 so the new number is
6√5
ex 2. square root of 121
If it is a perfect square like 121 then you can find the new number
11 × 11 = 121
therefore the square root of 121 is 11
Hope this helps
