Answer from: NateTheBeast12

C. $\sqrt{x}+3=13$

Step-by-step explanation:

We know that,

A radical equation is the equation in which the variable is under the radical.

According to the options, we see that,

In the equation $\sqrt{x}+3=13$ , the variable is under the radical.

All other equations have constant number under the radical.

Thus, we get,

Equation C i.e. $\sqrt{x}+3=13$ is a radical equation.

Answer from: morganruhl2

$\fbox{\text{Option C}}$ is correct as $\sqrt x+3 = 13$ is radical equation because the variable is under the radical and the radicand is .

Further explanation:

Radical can be describing as a square root, a cube root, a fourth root or higher root.

Radical equation can be defined as any equation that contains a radical on the variable is known as the radical equation.

The term under the radical symbol is known as radicand.

Option A is not correct.

Here, $x\sqrt 3= 13$ is not radical equation because the radical is on a constant term 3 not on the variable.

Option B is not correct.

Here, $x+\sqrt 3=13$ is not radical equation because the radical is on a constant term 3 not on the variable.

Option C is correct.

Here, $\sqrt x+3=13$ is radical equation because the variable is under the radical and the radicand is .

Option D is not correct.

Here, $x+3 =\sqrt {13}$ is not radical equation because the variable is not under the radical.

The equation $\sqrt x+3=13$ is a radical equation. Therefore $\fbox{\text{Option C}}$ is correct.

Answer from: Quest

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
