Simplifying
Rationalize the denominator of by multiplying both the numerator and denominator by to eliminate the radical from the denominator.
Step 1 — Multiply both the numerator and denominator by . To keep the fraction equivalent, both parts must be multiplied by the same value:
Step 2 — Simplify. In the denominator, . In the numerator, :
The simplified result is . Multiplying a square root by itself produces the radicand as an integer, which removes the radical from the denominator while the Equivalent Fractions Property guarantees that the new fraction has the same value as the original.
