Expanding binomials!!!

[From: ] [author: ] [Date: 11-12-23] [Hit: ]
i feel like its wrong,expanding using pascals triangle or whichever way you like. please!!!d^7 + 42d^6 + 756d^5 + 7560d^4 + 45360d^3 + 163296d^2 + 326592d + 279936-i also got d^7+42 d^6+756 d^5+7560 d^4+45360 d^3+163296 d^2+326592 d+279936 .......
quick question, it takes a lot of work but i really want to double check my work. i feel like its wrong, but what is

(d + 6)^7

expanding using pascals triangle or whichever way you like. please!!! i need it asap

d^7+42 d^6+756 d^5+7560 d^4+45360 d^3+163296 d^2+326592 d+279936

Via Pascal's Triangle:
1d^7 + 7(d^6)(6) + 21(d^5)(6^2) + 35(d^4)(6^3) + 35(d^3)(6^4) + 21(d^2)(6^5) + 7(d)(6^6) + 1(6^7)

Evaluating the coefficients gives:
d^7 + 42d^6 + 756d^5 + 7560d^4 + 45360d^3 + 163296d^2 + 326592d + 279936

i also got d^7+42 d^6+756 d^5+7560 d^4+45360 d^3+163296 d^2+326592 d+279936 .
