Answer 2

ANSWERS :

1 ) 5 i × - 3/5 i

i² = - 1

Cancel the two 5 s

==> - 3 i²

==> - 3 ( - 1 )

==> 3

ANSWER : 3

---------------------------------------

2 ) i¹⁹ + i¹⁹

==> i¹⁹ = i⁸⁽²⁾⁺³

==> i¹⁹ = i⁸⁽²⁾. i³ [ i⁸ = ( i²)⁴ = (-1)⁴ = 1 ]

==> i¹⁹ =  1 . - i [ i³ = - i ]

==> i¹⁹ = - i

Hence i¹⁹ + i¹⁹ = - i - i

                       = - 2 i

ANSWER :  - 2 i

--------------------------------------------------

3 ) i⁻³⁹ = 1 / i³⁹

==> 1 / i³⁶ . i³

Now : iⁿ where n is an even no. more than 2 is equal to 1

==> 1 / i³

==> i / i⁴

==> i / 1

ANSWER : i

Hope it helps :-)
