Question

Determine(5aelevado4-dois a elevado a 2+3a-1)-(2a elevado 3+6a elevado2-5a)+(-5 elevado4 + a elevado 3-2a+7) e dê o grau

Answer 1

(5a⁴-2a²+3a-1)-(2a³+6a²-5a)+(-5⁴+a³-2a+7)
(625a-4a+3a-1)-(8a+36a-5a)+(-625+3a-2a+7)
625a-4a+3a-1-8a-36a+5a-625+3a-2a+7
624a-1-39a-625+3a-2a+7
624a-39a+1a-1-625+7
625a-39a-626+7
586a-619
