Question

Calcule o quinto elemento do desenvolvimento de (x+5)elevado a 10

Answer 1

(x+10)^10=

p+1=5

p=5-1

p=4

n=10

Tp+1=n!/(n-p)!p!×a^p.x^(n-p)

T4=10!/(10-4)!4!.(5)^4.x^(10-4)

T4=10!/6!4!×625.x^6

T4=10.9.8.7.6!/6!4!×625x^6

T4=5040/24×625x^6

T4=210.625x^6

T4=13250x^6

espero ter ajudado!

boa tarde!
