Help Me Please.
Imaginary Numbers
\(\sqrt{-49} + \sqrt{-64}\)
sqrt (-49) + sqrt (-64)=
sqrt(49 x (-1)) + sqrt( 64 x (-1)
= 7 x sqrt(-1) + 8 sqrt(-1) (remember: sqrt(-1) is i )
= 7i + 8i
= 15 i
sqrt (-49) + sqrt (-64)=
sqrt(49 x (-1)) + sqrt( 64 x (-1)
= 7 x sqrt(-1) + 8 sqrt(-1) (remember: sqrt(-1) is i )
= 7i + 8i
= 15 i
