Question

Calcule a distancia entre A(2,3) e B(5,6)

Answer 1

d(A,B)=√(x2-x1)²+(y2-y1)²
Sendo x1=2, x2=5 , y1=3 e y2=6
d(A,B)=√(5-2)²+(6-3)²
d(A,B)=√3²+3²
d(A,B)=√9+9= √18=√2.3²= 3√2

Answer 2

Boa tarde 

Calcule a distancia entre A(2,3) e B(5,6)

dAB² = (Ax - Bx)² + (Ay - By)²
dAB² = (2 - 5)² + (3 - 6)²
dAB² = 9 + 9 = 18

dAB = 3√2
