Step-by-step explanation:
We want to find the value of k in
[tex] \sqrt{10k} + 3 = 5[/tex]
We subtract 3 from both sides;
[tex] \sqrt{10k} = 5 - 3[/tex]
Simplify on the right;
[tex] \sqrt{10k} = 2[/tex]
Square both sides;
[tex]10k = 4[/tex]
[tex]k = 0.4[/tex]
If your equation in actually
[tex] \sqrt{10k + 3} = 5[/tex]
Square both sides:
[tex]10k + 3 = 25[/tex]
[tex]10k = 22[/tex]
[tex]k = 2.2[/tex]
