The square root of 96 is the same thing as the square root of (16 x 6),
and that in turn is (√16) times (√6) .
We know the square root of 16 right away, so we can write
√96 = 4 √6 .
You have asked what goes into that 3 times. "Goes into..." is just
another way of stating division.
What goes into 4√6 three times is (4/3) √6 .
That number is about 3.266 (rounded) .
