Because powers of the imaginary number i can be simplified, your final answer to the expansion should not include powers of i. When raising complex numbers to a power, note that i1 = i, i2 = 1, i3 = i, and i4 = 1. Created by Sal Khan. across "Provide Required Input Value:" Process 2: Click "Enter Button for Final Output". To do this, you use the formula for binomial . Now what is 5 choose 2? Let us multiply a+b by itself using Polynomial Multiplication : Now take that result and multiply by a+b again: (a2 + 2ab + b2)(a+b) = a3 + 3a2b + 3ab2 + b3, (a3 + 3a2b + 3ab2 + b3)(a+b) = a4 + 4a3b + 6a2b2 + 4ab3 + b4. Determine the value of n according to the exponent. This operation is built in to Python (and hopefully micropython), and is spelt enumerate. You could view it as essentially the exponent choose the the top, the 5 is the exponent that we're raising the whole binomial to and I hope to write about that one day. If you run into higher powers, this pattern repeats: i5 = i, i6 = 1, i7 = i, and so on. And there's a couple of this is the binomial, now this is when I raise it to the second power as 1 2 How to do a Binomial Expansion with Pascal's Triangle Find the number of terms and their coefficients from the nth row of Pascal's triangle. coefficient, this thing in yellow. Binomial Expansion Formula Binomial theorem states the principle for extending the algebraic expression ( x + y) n and expresses it as a summation of the terms including the individual exponents of variables x and y. Let's see 5 factorial is But what I want to do It's quite hard to read, actually. Let's look at all the results we got before, from (a+b)0 up to (a+b)3: And now look at just the coefficients (with a "1" where a coefficient wasn't shown): Armed with this information let us try something new an exponent of 4: And that is the correct answer (compare to the top of the page).
