Answer:

11. 333... which can also be written as 11 1/3.

Explanation:

Sure.

√(6c - 4) = 8

Squaring both sides:

6c - 4 = 64

6c = 64 + 4 = 68

c = 68/6

= 11. 333...

Answer:


c=(34)/(3)

Explanation:

Given equation:


√(6c-4)=8

Square both sides:


\implies (√(6c-4))^2=8^2


\implies 6c-4=64

Add 4 to both sides:


\implies 6c-4+4=64+4


\implies 6c=68

Divide both sides by 6:


\implies (6c)/(6)=(68)/(6)


\implies c=(34)/(3)

Verify the solution by inputting the found value of c back into the equation:


\implies \sqrt{6\left((34)/(3)\right)-4}


\implies \sqrt{(204)/(3)-4}


\implies √(68-4)


\implies √(64)


\implies \pm 8

Therefore, the solution of the found value of c is verified.
