Question

o valor da expressão √x2 + y2 + 25 + 2xy + 10x + 10y
se x=17 e Y=23

Answer 1

Resposta:

√x2 + y2 + 25 + 2xy + 10x + 10y

se x=17 e Y=23

$\sqrt{X^2}+Y^2\:+25\:+\:2XY\:+10X$

$\sqrt{17^2}+23^2\:+25\:+\:2\left(17\cdot 23\right)\:+10\left(17\right)+10\left(23\right)$

$\sqrt{17^2}+23^2+25+2\left(17\cdot \:23\right)+10\left(17\right)+10\left(23\right)$

$\sqrt{17^2}$ = 17

$=17+23^2+25+782+170+230$

$\mathrm{Somar:}\:17+25+782+170+230=1224$

$=23^2+1224$

=529+1224

=1753
