a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
Just distribute the 3. 3(x + 4y) = 3x + 12y
3x + 12y is the answer.
The answer should be -40 + 16i
