$\frac{3+7i}{(2-5i)(1+3i)}$

2. anonymous

solve as in write in standard form?

3. anonymous

first multiply out in the denominator and get $\frac{3+7i}{17+i}$

4. anonymous

then multiply top and bottom by conjugate of the denominator, get $\frac{3+7i}{17+i}\frac{17-i}{17-i}$ denominator will be $17^2+1^2=290$ and the numerator will be whatever you get when you multiply

5. anonymous

it is clear how to multiply the two complex numbers? because that is the basic job here

6. anonymous

Yes i think so.
