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
