If Rational Quantities are joined to Surd Quantities of the fame Kind, divide the Rational by the Rational, if it can be done, and to the Quotient join the Quotient of the Surd, divided by the Surd, with its firft radical Sign. WHE HEN the Surds are not joined to rational Quantities, they are involved to the faine Height as their Index denotes, by taking away their radical Sign. When Surds are joined to rational Quantities, involve the rational Quantities to the fame Height as the Index of the Surd denotes; then multiply the involved Quantities into the Surd Quantities, after the radical Sign is taken away, as before.
