Mayemavins:.........1 .......1 1 ......1 2 1 .....1 3 3 1 ....1 4 6 4 1 ..1 5 10 10 5 1 .1 6 15 20 15 6 1 Above is the Pascal's triangle. So we are going to use the row 1 4 6 4 1 as our coefficient for the expansion. Since it's power four in (2a+3b)⁴ Hence: (2a +3b)⁴ = 1*(2a)⁴ + 4*(2a)³(3b) + 6*(2a)²(3b)² + 4*(2a)(3b)³ + 1*(3b)⁴ =16a⁴ + 96a³b + 216a²b² + 216ab³ + 81b⁴ The coefficients of (A + B)**5 are 1 5 10 10 5 1 The coefficients of (A+ B)**6 are 1 6 15 20 15 6 1 Oyya bless my azza WEMA Bank:7811737820 24 Likes 2 Shares |

[quote author=deen84 post=116317460][/quote] No the power of the expression you are expanding should be similar to the number after 1 in the row of the Pascal's triangle |

qwertyboss: Which one be Pascal triangle again. |
Re: 2k For Anyone Who Can Solve This For Me....mathematicians Food Don Land by qwertyboss(m): 6:14pm On Sep 03, 2022 |
MyVILLAGEpeople:The coefficients of the terms of an algebraic expression: Like X has 1 as it's coefficient X+Y has 1 and 1 as coefficients of it terms (X+y)²= x²+2xy+y² has 1, 2 and 1 as coefficients of it terms (X+y)³=x³+3x²y+3xy²+y³ has 1, 3, 3 and 1as it's coefficient. So Blaise Pascal a renown scientists discover tha the coefficients forms a triangle starting from a single to a triple term... .......1 single term expression ......1 1 double term expression .....1 2 1 triple term expression So Pascal's observed that the coefficients for quadruple term can be obtained by adding the first two terms of the previous coefficients in sequence after putting down 1 as the first and last coefficients of the current expression. Like 1 (1+2) (2+1) 1 which gives 1 3 3 1 Which corresponds to the coefficients of the expansion of (X+y)³ The next row of coefficients can also be obtained using 1 3 3 1 As 1 (1+3) (3+3) (3+1) 1 which gives 1 4 6 4 1 An expansion for (X+y)⁴ That's how he construct the traingle which can be applied to expansion of higher polynomials with ease like (X+y)¹² and so on before the discovery of permutation and combination which further makes the process very easier by eliminating the need for the triangle 14 Likes 1 Share |

FatherCHRISTMAS:That's mathematics for you You know they said understanding the question is half of the answer... The post is properly written as (2a + 3b)⁴... I believe many people skipped it because they didn't comprehend (2a + 3b)*4 because one * means multiplication, is double ** that means raised to the power of... After all this is just a silly maths compare to advance power series like the Tailor's, Fourier's or McLaren's series 6 Likes |

qwertyboss:You reminded me of my days when I was seriously tackling engineering mathematics. I was 17 then. I did up to Laplace transform. I loved Taylor series and McLaren series. I didn't have time to learn Fourier series. I could remember reduction formula in integration calculus,Surface of a revolution,Partial derivatives, 2nd order differential equation. The irony of all these is that I ended up with excel I'm a chartered accountant now. I was not originally from the science field. I loved maths so much like you.

How can you give someone who demystified this get 2k? D person deserves at least 10k or more Even if he or she was wrong, the person should get 5k for attempting such! |

qwertyboss: Unfortunately there was a mistake in your calculation. I am surprised no one caught it. 432 should be 216. The concept is correct but computation wrong. |
