Sum of complex numbers (a1+b1i)+(a2+b2i)=(a1+a2)+(b1+b2)i=a+bi  (1+2i)+(1+3i)=(1+1)+(2+3)i=2+5i this is the binomial form  Then find r and θ  r=a2+b2=22+52=29  if a and b are possitive then  θ=tan−1⁡(ba)=tan−1⁡(52)=68.2∘  Rectangle form  z=r(cos⁡(θ)+sin⁡(θ)i)  then z=29(cos⁡(68.2)+sin⁡(68.2)i)

Answer:(1+2j)+(1+3j)=2+5jExplanation:Given:(1+2j)+(1+3j)We can group the real and imaginary parts:(1+1)+(2j+3j)Simplifying the real part:1+1=2Simplifying the imaginary part:2j+3j=5jCombining the real and imaginary parts, we get the result:2+5jTherefore, (1+2j)+(1+3j)=2+5j.

Let&#039;s start by adding the real parts together:(1+2j)+(1+3j)=1+1+2j+3jNext, we add the imaginary parts together:=2+5jTherefore, the sum of (1+2j)+(1+3j) is 2+5j.In rectangular form, the complex number 2+5j can be represented as 2+5i, where i is also used to denote the imaginary unit.

To solve the expression (1+2j)+(1+3j) in rectangular form, we simply add the real parts and the imaginary parts separately. The real part is obtained by adding the real parts of the complex numbers, and the imaginary part is obtained by adding the imaginary parts.Let&#039;s break down the calculation:Real part: 1+1=2Imaginary part: 2j+3j=5jPutting it all together, the sum of (1+2j)+(1+3j) is 2+5j.Hence, the result in rectangular form is 2+5j.
