Evaluate the following: i^(19)

Write the complex numbers in the form A+iB i^(-19)

Express the following in the form a + ib i^(-19)

Evaluate: " "(i)" "i^(19)" "(ii)" "i^(62)" "(iii)" "i^(373)

Evaluate the following: (i) i^(135) " "(ii) i^(19) " " (iii) i^(-999) " " (iv) (-sqrt(-1))^(4n + 2), n in N .

Simplify [(i^(4)+i^(9)+i^(16))/(3-2i^(5)-i^(10)-i^(15))]^(10)

i^(9)+i^(10)-3i^(12)=-4

Simplify: (4i^9-3i^9)
