Simplify the squareroot of (12)

√12

First find the highest perfect square that can go into it.

1, 4, 9, 16

The highest square is 4 (2^2)

To take out 4 from √12, put the root of four multiplied by the root of the quotient of 12 and 4 (the quotient of 12 and 4 should become the radicand).

Final answer: 2√3
