If you have 2 of the same factor in a square root you take them out but just write one.

Looking at \sqrt{363}
\sqrt{363} = \sqrt{3*11*11} =11 \sqrt{3}

Looking at 3 \sqrt{27}
3\sqrt{27}=3 \sqrt{3*3*3}  = (3*3)\sqrt{3} =9 \sqrt{3}

Put them back together:
11 \sqrt{3} -9 \sqrt{3} =2 \sqrt{3}

. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form
saw5 [17]
Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

\bf \textit{area of a rectangle}\\\\
A=length\cdot width\quad 
\begin{cases}
length=x\\
width=x\\
A=112
\end{cases}\implies 112=x\cdot x\implies 112=x^2
\\\\\\
\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x
