Question 28

Multiple Choice

Perform the indicated operation using the standard form.​ 5i(1−2i) 5 i ( 1 - \sqrt { 2 } i ) ​


A) 5i(1−2i) ≈7.07+5i5 i ( 1 - \sqrt { 2 } i ) \approx 7.07 + 5 i
B) ​ 5i(1−2i) ≈5+7.07i5 i ( 1 - \sqrt { 2 } i ) \approx 5 + 7.07 i
C) ​ 5i(1−2i) ≈1+52i5 i ( 1 - \sqrt { 2 } i ) \approx 1 + 5 \sqrt { 2 i }
D) ​ 5i(1−2i) ≈5−7.07i5 i ( 1 - \sqrt { 2 } i ) \approx 5 - 7.07 i
E) ​ 5i(1−2i) ≈7.07−5i5 i ( 1 - \sqrt { 2 } i ) \approx 7.07 - 5 i
