Question

Find the value of | -2i ( 3 + i ) ( 2 + 4i ) ( 1 + i ) | ​

Answer 1

Step-by-step explanation:

|-2i(6+12i+2i+4i^2)(1+I)|

|-2i(6+14i+4j^2)(1+I)|

|-2i(6+14i+4i^2+6i+14i^2+4i^3)|

|-2i(6+20i+18i^2+4i^3)|

|-2i(6+20i+18(-1)+4(-i)|

|-2i(6+20i-18-4i)|

|-2i(-12+16i)|

|24-16i|

√(24)^2+(-16)^2

√576+256

√832
