$sqrt(94)$

The distance formula between two points in 2D is $sqrt((x_1-x_0)^2+(y_1-y_0)^2$ .

The distance formula between two points in 3D is similar: $sqrt((x_1-x_0)^2+(y_1-y_0)^2+(z_1-z_0)^2)$ .

We just need to substitute the values in: $sqrt((x_1-x_0)^2+(y_1-y_0)^2+(z_1-z_0)^2)=sqrt((-9-(-6))^2+(10-3)^2+(2-(-4))^2)=sqrt(94)$ .

What is the distance between (-6,3,-4)(-6,3,-4) and (-9,10,2)(-9,10,2)?
