so you find pairs of factors and gropu
factor 96
96=2 times 2 times 2 times 2 times 2 times 3
group pairs of same numbers
96=(2 times 2) times (2 times 2) times 2 times 3
so now
√96=[tex] \sqrt{(2 times 2) times (2 times 2) times 2 times 3} [/tex]=[tex] 2 times 2\sqrt{2 times 3} [/tex]=[tex] 4\sqrt{6} [/tex]
answer is [tex] 4\sqrt{6} [/tex]
