Answer:[tex]D=\sqrt{10}[/tex]

Step-by-step explanation:

Given

circle

[tex]\left ( x-1\right )^2+\left ( y+2\right )^2=16[/tex]

center of circle is (1,-2)

second circle

[tex]\left ( x+2\right )^2+\left ( y+1\right )^2=14[/tex]

center of circle is (-2,-1)

Distance between two points

[tex]D=\sqrt{\left ( y_2-y_1\right )^2+\left ( x_2-x_1\right )^2}[/tex]

[tex]D=\sqrt{\left ( -2+1\right )^2+\left ( 1+2\right )^2}[/tex]

[tex]D=\sqrt{10}[/tex]
