Answer:
Step-by-step explanation:
[tex]\sf \sqrt{-9} +\sqrt{-16}[/tex]
First, Simplify √(-9) to √(9i):
[tex]\sf \sqrt{9i} +\sqrt{-16}[/tex]
Since 3 * 3= 9, square root of 9 is 3.
[tex]\sf 3i+\sqrt{-16}[/tex]
Now, Simplify √(-16) to √(16i):
[tex]\sf 3 +\sqrt{16i}[/tex]
Now, since 4*4 = 16, the square root of 16 is 4.
[tex]\sf 3i+4i[/tex]
Simplify.
[tex]\sf 7i[/tex]
