Question

Sabendo que w = 3 e k=-1. qual o valor da expressão V3w + 5k?​

Answer 1

$\large\boxed{\begin{array}{l}\rm \sqrt{3w}+5k\bigg|_{w=3~~k=-1}=\sqrt{3\cdot3}+5\cdot(-1)\\\\\rm\sqrt{3w}+4k\bigg|_{w=3~k=-1}=\sqrt{9}-5\\\\\rm\sqrt{3w}+5k\bigg|_{w=3~k=-1}=3-5\\\\\rm \sqrt{3w}+5k\bigg|_{w=3~k=-1}=-2\end{array}}$
