simplify (sqrt(49)-sqrt(-36))+(sqrt(9)-sqrt(-16))

simplify

(49 - - 36) + (9 - - 16)

10 - 10 i

Solution steps

(49 - - 36) + (9 - - 16)

(49 - - 36) + (9 - - 16) = 49 - - 36 + 9 - - 16

= 49 - - 36 + 9 - - 16

49 = 7

- 36 = 6 i

9 = 3

- 16 = 4 i

= 7 - 6 i + 3 - 4 i

Group like terms

= - 6 i - 4 i + 7 + 3

Add similar elements:

- 6 i - 4 i = - 10 i

= - 10 i + 7 + 3

Add the numbers:

7 + 3 = 10

= - 10 i + 10

Rewrite in standard complex form:

10 - 10 i

= 10 - 10 i
