does 8 have a perfect square that we can factor out of it?

anonymous · Answer

no

amistre64 · Answer

are you sure?

I would assume that 4 * 2 = 8 ... and that 4 is a perfect square

anonymous · Answer

oh ok sorry i thought you meant it had to be like 4 *4

anonymous · Answer

then yes it does

amistre64 · Answer

sqrt(4) * sqrt(2) = 2sqrt(2)  would you agree?

anonymous · Answer

yes

amistre64 · Answer

the bottom is a perfect square:

sqrt(16) = 4 right?

so we simplify it as....

2sqrt(2)                                                   sqrt(2)
------  which can be simplified further to ------; do you agree?
    4                                                            2
