Problem
Solution
For this case we can do the following:
[tex](4+\sqrt[]{-49})-2(\sqrt[]{(-4)^2}+\sqrt[]{-324})\text{ }[/tex]
We also know that :
[tex]\sqrt[]{-1}=i[/tex]
Using this property we got:
[tex](4+7i)-2(4+18i)[/tex]
Now we can distirbute the terms and we got:
4+7i -8 -36 i
And distributing the terms we got:
(7-36)i +(4-8)
-29 i -4
And then our solution would be:
a= -29
b= -4
