Radical: square roots and higher roots Shorthand method of writing roots
z
Some roots are ‘rational’ rational
z
Some roots are ‘irrational’
z
• Use fractional exponent p • Not necessarily a fractional value of exponent • Can be written as a ratio: exact value • Can onlyy be written exact in ‘root’ form
