−6i−44−−−−√
Enter your answer, in simplest radical form, in the box.
Now it is correct.
-6i · sqrt( -44 )
Since sqrt( -44 ) = i · sqrt( 44 )
= i · sqrt( 4 ) · sqrt( 11 )
= i · 2 · sqrt( 11 )
= 2i · sqrt( 11 )
-6i · sqrt( -44 ) = -6i · 2i · sqrt( 11 )
= -12 · i2 · sqrt( 11 )
Since i2 = -1:
= -12 · -1 · sqrt( 11 )
= 12· sqrt( 11 )
