Cube root of c to the third is c.

So C is equal to, X times the square root of 2.

That's already a perfect cube. c to the third, the cube root of that is c, so times c to the third.

This is the same thing as the cube root of 8 that's the first term right there times the cube root of b cubed times the cube root of c cubed.

Ok, to C squared, now let's take the principle root of both sides of that.

And notice, I'm only taking the principal root here, because c has to be positive.

So you're going to have X times the square root of 2 is equal to, C.

Negative b plus or minus the square root of b squared minus 4 times a times c.

The principle root is a positive root.

4 square root, principle root is 2.

So minus 5 plus or minus the square root of b squared, so 25, minus 4 times a. times 8, times c. c is minus 42.

Let me rewrite it over here. c squared is equal to 130, or we could say that c is equal to the square root of 130.

And they give these choices. a), square root of x, b), square root of x squared plus 1, which we just figured out was actually the answer. c), x, d), x squared.

It's 18 plus or minus the square root of 18 squared minus 4 times 3 times c times 37.

Times the principle root of 5 times the principle root, times the principle root of x squared times the principle root of x.

Square root of three times square root of three

We're taking the principal root, the positive square root.

So square root of 45, so the square root of 45, or the principle root of 45.

So the square root of 12 is equal to square root of 3 times square root of 4.
