z1 =  \sqrt{ - 36 }  =  \sqrt{ - 1} \sqrt{36 }  =  \sqrt{36}i
z2 = \sqrt{ - 25} =  \sqrt{ - 1} \sqrt{25 } =  \sqrt{25}i
z3 =  \sqrt{ - 16} =  \sqrt{ - 1} \sqrt{16 } =  \sqrt{16}i
Now
z1 + z2 + z3 =  \sqrt{36}i +  \sqrt{25}i +  \sqrt{16}i
 = 6i + 5i + 4i
 = 14ior \sqrt{196( - 1)} =  \sqrt{ - 196}

Answer:

15i

Step-by-step explanation:

z1 = √-36 = √(-1)36 = √36i

z2 = √-25 = √(-1)25 = √25i

z3 = √-16 = √(-1)16 = √16i

Now adding z1,z2 and z3;

√36i + √25i + √16i

=6i + 5i + 4i

=15i

and this is your answer (•_°)
