Question

Can someone solve this and show me the work √5k+2 +8=11

Answer 1

Simple...

you have: $\sqrt{5k} +2+8=11$

-->>Isolate the variable...

$\sqrt{5k} +2+8=11$

$\sqrt{5k} +10=11$

$\sqrt{5k} +10=11$
                       -10  -10

$\sqrt{5k} =1$

What is the opposite of square root? $(x)^{2}$

$\sqrt{5k} ^{2} = 1^{2}$

5k=1

Now simply divide-->>

k=$\frac{1}{5}$

Thus, your answer.
