simplify (i^2+3)-(7+i^3)

Solution

simplify

(i^{2} + 3) - (7 + i^{3})

Solution

- 5 + i

Solution steps

(i^{2} + 3) - (7 + i^{3})

Apply rule:

(a) = a

(i^{2} + 3) = i^{2} + 3

= i^{2} + 3 - (7 + i^{3})

i^{2} = - 1

- (7 + i^{3}) = - 7 + i

= - 1 + 3 - 7 + i

Add the numbers:

- 1 + 3 - 7 = - 5

= - 5 + i
