Question 12163
Look for a perfect square, the largest one you can find, that divides evenly into 176.  It just so happens that 4 and 16 both divide evenly, so choose the larger of these, and break the number 176 down into a product of 16 times 11.


{{{sqrt(176) = sqrt(16)*sqrt(11) }}}


Everyone knows that {{{sqrt(16) = 4}}} and no one can simplify {{{sqrt(11) }}}.  So, 


{{{sqrt(176) = sqrt(16)*sqrt(11) }}}

{{{sqrt(176) = 4*sqrt(11) }}}
