i^(30)+i^(40)+i^(60)

Write the value of i+i^(10)+i^(20)+i^(30)

What is the vlaue of 1+i^(2)+i^(4)+i^(60)+....+i^(100), where i=sqrt(-1) ?

Show that 1+i^(10)+i^(20)+i^(30) is a real number.

Show that 1+i^(10)+i^(20)+i^(30) is a real number.

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

(i^(65)+i^(54)+i^(30)) =

Evaluate the following: i^30 + i^40 + i^50 + i^60

Simplify the following : (i) i^7 " " (ii) i^(1729) " " (iii) i^(-1924) + i^(2018) " " (iv) sum_(n=1)^(102) i^(n) " " (v) i i^2 i^3 …..i^(40)
