It is called rationalising the denominator.
Rationalising the denominator.
Multiply the numerator and denominator by the complex conjugate of the denominator ... [ root(2) minus i ]. This process is called 'rationalizing the denominator'.
Similar radicalssuch as ... 5(sq root 7) + 3(sq root 7) are similar because the radical has the same root index and the same number inside the radical. Like variables they can have different coefficients. 2x and 5x are similar ( called like terms) add the coefficients. 2x + 5x = 7x similarly 5(sq root 7) + 3(sq root 7) = 8(sq root 7)
