Fractions involving surds. As in the last worksheet on algebraic fractions, fractions involving surds are worked out simi-larly to fractions involving numbers. When adding and subtracting fractions the denominators must be the same for all the fractions involved in the calculation.
Surds are basically an expression involving a root, squared or cubed etc... There are some basic rules when dealing with surds. Example: √36 = 6. The above roots have exact values and are called Rational. Example: √2 = 1.41.
