write the complex number in standard form a+bi

Question

sqrt 7 (cos pi/12 + i sin pi/12)

(sqrt = square root, i= imaginary number)

Answer 1

check condition of problem

Answer 2

what do you mean?

Answer 3

Maybe we must find the square of
sqrt7(cosPi/12+isinPi/12)?
sqrt7=2.646
cosPi/12=0.966
sinPi/12=0.259
2.646(0.966+i0.259)=2.556+0.685i

Answer 4

thank you
