simplify (i+1)^{11}

Solution

simplify

(i + 1)^{11}

Solution

- 32 + 32 i

Solution steps

(i + 1)^{11}

Apply binomial theorem:

(a + b)^{n} = i = 0 \sum n (i n) a^{(n - i)} b^{i}

a = i, b = 1

= i = 0 \sum 11 (i 11) i^{(11 - i)} \cdot 1^{i}

Expand summation

Simplify

\frac{11 !}{11 ! ( 11 - 11 ) !} i^{0} \cdot 1^{11} : 1

= i^{11} + 11 i^{10} + 55 i^{9} + 165 i^{8} + 330 i^{7} + 462 i^{6} + 462 i^{5} + 330 i^{4} + 165 i^{3} + 55 i^{2} + 11 i + 1

Simplify

i^{11} + 11 i^{10} + 55 i^{9} + 165 i^{8} + 330 i^{7} + 462 i^{6} + 462 i^{5} + 330 i^{4} + 165 i^{3} + 55 i^{2} + 11 i + 1 : 32 i - 32

= 32 i - 32

Rewrite in standard complex form:

- 32 + 32 i

= - 32 + 32 i
