Power Property of Equality

Power Property of Equality

The Power Property of Equality states that raising each side of an equation with the same number yields an equivalent equation.

If

a = b,

then

a^{m} = b^{m} .

This property can be used when solving equations when the equation can be rewritten to have both sides raised to the same power.
