- How do you simplify #(3 + 2i)(2 − i)# and write in a+bi form?8+i You can simply multiply the two parenthesis as you do with normal number, and then remember that you can sum immaginary numbers (e.g. 3i+5i=8i) and that i^2=-1.
- The Mole - Chemistry - SocraticA mole is the fundamental unit of chemistry. It is defined by avogradro's number 6.02 × 10^23. A mole is the quantity of any molecule, atom, etc that has the same number of particles found in 12.000 grams of carbon-12.
- How do I use DeMoivre's theorem to solve z^3-1=0? - SocraticIf z^3-1=0, then we are looking for the cubic roots of unity, i.e. the numbers such that z^3=1. If you're using complex numbers, then every polynomial equation of degree k yields exactly k solution. So, we're expecting to find three cubic roots. De Moivre's theorem uses the fact that we can write any complex number as \\rho e^{i \\theta}= \\rho (\\cos(\\theta)+i\\sin(\\theta)), and it states ...
- How do you find the absolute value of 3+4i? - Socratic|a + bi| is not read as the absolute value of a + bi; it is read as the magnitude of a + bi: |3 + 4i| = sqrt(3^2 + 4^2) = 5 The |a + bi| is not read as the absolute value of a + bi; it is read as the magnitude of a + bi. The magnitude is calculated, using the equation: |a + bi| = sqrt(a^2 + b^2) |3 + 4i| = sqrt(3^2 + 4^2) = 5
