I^3 + i^19 + i^16
simplify completely and show all work

1-2i

Step-by-step explanation:

1: Evaluate the power, so i^3 and i^19 become negative because they have odd exponents. i^16 becomes a positive 1 because they have even exponents.

-i-i+1

2. Combine like terms. -2i+1

3. Reorder terms

Solution: 1-2i

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
