# Math Help - the quare foot of 124

1. ## the quare foot of 124

how would you simplfy the square root of 124
when you simplify the square root of 125 you can have 5 squareroots of 3
taht is what i mean

2. Hello,

124=2*62=2*2*31

So d'you have an idea on how to simplify ?

3. Find the biggest factor of 124 that is a perfect square and use the property that: $\sqrt{a \cdot b} = \sqrt{a} \cdot \sqrt{b}$

Also, $\sqrt{125} \neq 5\sqrt{3}$. Using what I told you above:

$\sqrt{125} = \sqrt{25 \cdot 5} = \sqrt{25} \cdot \sqrt{5} = 5 \sqrt{5}$

Ah ok Moo beat me.
