[" 2."i^(9)+i^(19)," 3."i^(-39)]

Find i^(9)+i^(19)

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

Express the complex number (i) i^(9)+i^(19) (ii) i^(-39) in the form a+ib .

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

Simplify ( i ^( 29) + i ^( 39) + i ^( 49))/( i ^(30) + i ^(40) + i ^(50))

simplify the following 2i^(2)+6i^(3)+3i^(16)-6i^(19)+4i^(25)

Prove that: (i) (1-i)^(2)=-2i (ii) (1+i)^(4)xx(1+(1)/(i))^(4)=16 (iii) {i^(19)+((1)/(i))^(25)}^(2)=-4 (iv) i^(4n)+i^(4n+1)+i^(4n+2)+i^(4n+3)=0 (v) 2i^(2)+6i^(3)+3i^(16)-6i^(19)+4i^(25)=1+4i .

Simplify : i^(9)+i^(19) ?

Evaluate 2i^(2)+ 6i^(3)+3i^(16) -6i^(19) + 4i^(25)

Evaluate 2i^(2)+ 6i^(3)+3i^(16) -6i^(19) + 4i^(25)
