Question

calcule o valor de p (x)=x -3x+5 x =
$\sqrt{3}$
​

Answer 1

$p(x) = x ^{4} - 3x ^{2} + 5x \\ para \: x = \sqrt{3} \\ p( \sqrt{3}) = ( \sqrt{3}) ^{4} - 3( \sqrt{3}) ^{2} + 5( \sqrt{3}) \\ p( \sqrt{3}) = \sqrt{81} -3( \sqrt{9} ) + 5 \sqrt{3} \\ p( \sqrt{3}) =3 \sqrt{9 } - 3 \sqrt{9} + 5 \sqrt{3} \\ p( \sqrt{3)} = 5 \sqrt{3}$
