Root of a Complex Number

n = 5
z = 2 + 2i
k = 3

5 √ ( 2 + 2 i ) 3 : -0.87055056 - 0.87055056 i



Operations with complex numbers :

Example 1:

( ( ( ( 2 + 3 i ) * 2 i + 3 i - 7 ) * 2 i - 9 ) * 7 i ) * -2 i

+ ( 1 - 3 i ) * ( 3 + 6 i ) - ( 2 * 3 i - 7 + 8 i ) + ( 2 - 9 i ) ^ 2


Example 2:

5 + 3 i + 4 √ ( 2 + 2 i ) 2 - 7 * 7 i + 2 √ 25 + 4


Example 3:

3 √ ( ( 1 + i ) / ( 2 √ 3 + i ) ) 2




Permutations m!/(m-n)! : P( 8 4 )


Combinations m!/(m-n)!.n! : C( 5 3 )


Permutations with repetition m = a + b + c + .....

m!/(a!.b!.c!....) : PR( 7 8 4 5 )


Example 3:

PR( 7 8 4 5 ) + C( 5 3 ) - P( 8 4 ) * 5! + 8 + 2,5 % 5000


Example 4:

Log 4 - Ln 8 + Log( 4 48 ) + ( sin 45 i + cos 45 ) ^ 2
