Solve 2R=4*2/sqrt{2}

$$2 R = 4 \times \frac { 2 } { \sqrt { 2 } }$$

Solve for R

$$R=2\sqrt{2}\approx 2.828427125$$

Steps for Solving Linear Equation

Rationalize the denominator of \frac{2}{\sqrt{2}} by multiplying numerator and denominator by \sqrt{2}.

$$2R=4\times \frac{2\sqrt{2}}{\left(\sqrt{2}\right)^{2}}$$

The square of \sqrt{2} is 2.

$$2R=4\times \frac{2\sqrt{2}}{2}$$

Cancel out 2 and 2.

$$2R=4\sqrt{2}$$

Divide both sides by 2.

$$\frac{2R}{2}=\frac{4\sqrt{2}}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$R=\frac{4\sqrt{2}}{2}$$

Divide 4\sqrt{2} by 2.

$$R=2\sqrt{2}$$
