Question

What is the value of k if √10 * k + 3 = 5?

Answer 1

Answer:

See explanation

Step-by-step explanation:

We want to find the value of k in

$\sqrt{10k} + 3 = 5$

We subtract 3 from both sides;

$\sqrt{10k} = 5 - 3$

Simplify on the right;

$\sqrt{10k} = 2$

Square both sides;

$10k = 4$

$k = 0.4$

If your equation in actually

$\sqrt{10k + 3} = 5$

Square both sides:

$10k + 3 = 25$

$10k = 22$

$k = 2.2$
