Question 73482
#6 ... when you find the sqrt of a number, the radical disappears.  And the - sign makes this an imaginary number, the neg comes out and becomes an 'i'
{{{ sqrt(-121) = 11i }}}


#12 Again the radical disappears
{{{ sqrt(4/25) = 2/5 }}}


#24 CORRECT!!!


#2 Continue on ...
{{{ sqrt(50) }}}
{{{ sqrt(2*5*5) }}}
{{{ 5sqrt(2) }}}


#24 Continue on ...
{{{ sqrt(72x^3) }}}
{{{ sqrt(2*2*2*3*3*x*x*x) }}}
{{{ (2*3*x)sqrt(2x) }}}
{{{ (6x)sqrt(2x) }}}
