Question

What is the expansion of the binomial (2k+4)^4?

Answer 1

Do you know about binomial expansion? I'll teach it to you by Pascal's triangle ^_^

Answer 2

Check out the last line. The last line is known as line 4. That states the coefficients.

Answer 3

I actually got to use pascals triangle to derive a laplace transform for some series. was pretty cool

Answer 4

Yeah I do, I mean i've learned it. I am currently doing quiz corrections and my final answer was 2k^4+32k^3+192k^2+512k+256

Answer 5

And, the first term will have the exponent of 2k as 4, and exponent of 4 as 0.
Then the second one will have the exponent of 2k as 3 and exponent of 4 as 1.

Answer 6

Remember to put the brackets and simplify expressions such as (2k)^4

Answer 7

Umm I get 16k^4 in the first term.

Answer 8

Erm, can you try that again please?

Answer 9

Shizzz, was I supposed to do 2^4 then that would equal 16k^4?

Answer 10

Yeppp

Answer 11

I am oficially a dumb retricesssssss. Hahahah

Answer 12

(2k)^4 = 16k^4

Answer 13

lol no it's good that you are doing it yourself :)

Answer 14

I meant to say donkey but it didn't let me. :(

Answer 15

I have another probability one then i am done i will repost it.

Answer 16

Sure!
