Solve 100=2sqrt{3.2h}

$$100 = 2 \sqrt { 3.2 h }$$

Solve for h

$$h=781.25$$

Steps for Solving Radical Equations

Divide both sides by 2.

$$\frac{100}{2}=\sqrt{3.2h}$$

Divide 100 by 2 to get 50.

$$50=\sqrt{3.2h}$$

Swap sides so that all variable terms are on the left hand side.

$$\sqrt{3.2h}=50$$

Square both sides of the equation.

$$3.2h=2500$$

Divide both sides of the equation by 3.2, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{3.2h}{3.2}=\frac{2500}{3.2}$$

Dividing by 3.2 undoes the multiplication by 3.2.

$$h=\frac{2500}{3.2}$$

Divide 2500 by 3.2 by multiplying 2500 by the reciprocal of 3.2.

$$h=781.25$$
