Q. 11i(8+10i)= 11 i \cdot(-8+10 i)= \newlineYour answer should be a complex number in the form a+bi a+b i where a a and b b are real numbers.
  1. Write down complex numbers: Write down the complex numbers to be multiplied.\newlineWe have two complex numbers: 11i11i and (8+10i)(-8+10i). We need to multiply these two complex numbers together.
  2. Use distributive property: Use the distributive property to multiply the complex numbers.\newlineMultiplying 11i11i by each term in the complex number (8+10i)(-8+10i) gives us:\newline11i(8)+11i(10i)11i \cdot (-8) + 11i \cdot (10i)
  3. Calculate the products: Calculate the products.\newline11i×(8)=88i11i \times (-8) = -88i (since ii is the imaginary unit and 8-8 is a real number)\newline11i×(10i)=110i211i \times (10i) = 110i^2 (since i×i=i2i \times i = i^2)
  4. Simplify the expression: Simplify the expression.\newlineWe know that i2=1i^2 = -1, so we can replace i2i^2 with 1-1 in the expression:\newline88i+110(1)-88i + 110(-1)\newlineThis simplifies to:\newline88i110-88i - 110
  5. Write final answer: Write the final answer in the form a+bia+bi. The real part aa is 110-110, and the imaginary part bb is 88-88. So the product of 11i11i and (8+10i)(-8+10i) is: 11088i-110 - 88i
