A formula é esta:
(a + b)^5 = a^5 + 5a^4b + 10a^3b^2 + 10a^2b^3 + 5ab^4 + b^5
Então:
 <span>(t+3)^5= t^5 + 5t^4\cdot3 + 10t^3\cdot 3^2 + 10t^2\cdot3^3 + 5t\cdot3^4 + 3^5</span> 
Simplificando:
(t+3)^5=t^5 + 5t^4\cdot3 + 10t^3\cdot9 + 10t^2\cdot27 + 5t\cdot 81+243
(t+3)^5=t^5 + 15t^4+ 90t^3 + 270t^2 + 405t +243
