plz answer it guys l need help​

Answer 1

Answer:

(i) 0 , (ii) 11i .

Step-by-step explanation:

$\sqrt{-1}$ = i  

(i) √16 × √(-1) + 3√25 × √(-1) + √36 × √(-1) - √625 × √(-1) =

4i + 15i  + 6i - 25i = 0

(ii) 4√4 × √(-1) + 5√9 × √(-1) - 3√16 × √(-1) =

8i + 15i - 12i = 11i

Answer 2

Step-by-step explanation:

✓1 = i

(i) √16 × √(-1) + 3√25 × √(-1) + √36 × √(-1) - √625 × √(-1) =

4i + 15i + 6i - 25i = 0

(ii) 4√4 × √(-1) + 5√9 × √(-1) - 3√16 × √(-1) =

8i + 15i - 12i = 11i
