try now..
ain't that difficult

Answer 2

√-16 + √-36
= 4i + 6i
= ..

Answer 3

so then it would be 10i

Answer 4

\[-16 = 4^2i^2\]

\[-36 = 6^2i^2\]

Put these values in square root brackets and then solve you will get your answer...

Answer 5

then would it be 10^2i*i^2 ?

Answer 6

ok i am lost sorry :(

Answer 7

they are making this way to hard look at callisto

Answer 8

6^2 = 36 and 4^2 = 16

Answer 9

To my knowledge
\[\sqrt{-16} +\sqrt{ -36}\]\[=\sqrt{-1\times 4^2} +\sqrt{ -1 \times 6^2}\]\[=4\sqrt{-1} +6\sqrt{ -1}\]\[=4i +6i\]\[=10i\]
