√96 = √16 * √6
√96 = √(4²) * √6
√96 = 4 * √6
√96 = 4√6
So 2√6 + 3√96 turns into 2√6 + 4√6

OpenStudy (anonymous):
2√6 + 4√6
we know that 2x+4x=6x, (think of "√6" as of "x")
so, 2√6 + 4√6 = ?

and the same way,
2√6 + 4√6 equals what ?
12 years ago
OpenStudy (anonymous):
(think of √6 as of a variable)
if 3x + 6x = 9x
then 3√4 + 6√4 = 9√4
and the same way is your problem
if 2x + 4x = 6x
then 2√6 + 4√6 = 6√6

2√6 + 3√96
√96 = √16 * √6
√96 = √(4²) * √6
√96 = 4 * √6
√96 = 4√6
so 2√6 + 3√96 turns into 2√6 + 3(4√6) which is same as 2√6 + 12√6
2√6 + 12√6 + equals to what ?
12 years ago
OpenStudy (anonymous):
we are substituting 4√6 instead of √96 because they are equal.
