√44
Find the factors of 44
Factors of 44: 1, 2, 4, 11, 22, 44
[1 · 44, 2 · 22, 4 · 11]
When you find the factors of 44, find the factor that can be square rooted (i don't know if that's a word but I'll go with it)
The factor that can be square rooted is 4, because √4 = 2
So you can do:
√44 = √(4 · 11) = √4 · √11 = 2 · √11 = 2√11
Your answer is:
2√11
