Question

Calcule a potência do ponto P e o valor de x.​

Answer 1

$\large\boxed{\begin{array}{l}\sf PA\cdot PB=PC\cdot PD\\\sf x\cdot\sqrt{2}=1\cdot \sqrt{3}\\\sf x=\dfrac{\sqrt{3}}{\sqrt{2}}\cdot\dfrac{\sqrt{2}}{\sqrt{2}}\\\\\sf x=\dfrac{\sqrt{6}}{\sqrt{2^2}}\\\\\sf x=\dfrac{\sqrt{6}}{2}\end{array}}$
