Final answer:
The root ratio in the word 'rationalize' refers to the process of eliminating square roots from denominators.
Step-by-step explanation:
The root ratio in the word 'rationalize' refers to the process of eliminating square roots from denominators. This is the correct answer option (b). When rationalizing a fraction, we multiply the numerator and denominator by the conjugate of the denominator, which eliminates the square root from the denominator and simplifies the expression. For example, if we have the fraction 1/sqrt(2), we can rationalize it by multiplying the numerator and denominator by sqrt(2), resulting in sqrt(2)/2. Therefore, option (b) best represents the meaning of the root ratio in the word 'rationalize.'
