Question

Sendo P(X) = 8x³ + 5x - 1 calcule P(1) ​

Answer 1

Resposta ↓

Valor de P(1) = 12

Explicação passo a passo:

⇒ Para resolvermos, substituímos P(x) por P(1):

$\boxed{\begin{array}{lr}{\sf P(x) = 8x^3 + 5x - 1 \end{array}}} \\\\\boxed{\begin{array}{lr}{\sf P(1) = 8.1^3 + 5.1 - 1 \end{array}}} \\\\\boxed{\begin{array}{lr}{\sf P(1) = 8.1 + 5 - 1 \end{array}}} \\\\\boxed{\begin{array}{lr}{\sf P(1) = 8+ 5 - 1 \end{array}}} \\\\\boxed{\begin{array}{lr}{\sf P(1) = 12 \end{array}}}$
