E=\frac{-4}{\left(1-i\right)^{7}}
Calculate 1+i to the power of 4 and get -4.
E=\frac{-4}{8+8i}
Calculate 1-i to the power of 7 and get 8+8i.
E=\frac{-4\left(8-8i\right)}{\left(8+8i\right)\left(8-8i\right)}
Multiply both numerator and denominator of \frac{-4}{8+8i} by the complex conjugate of the denominator, 8-8i.
E=\frac{-32+32i}{128}
Do the multiplications in \frac{-4\left(8-8i\right)}{\left(8+8i\right)\left(8-8i\right)}.
E=-\frac{1}{4}+\frac{1}{4}i
Divide -32+32i by 128 to get -\frac{1}{4}+\frac{1}{4}i.
