Two pair of numbers are said to be relatively prime if there is no integer greater than 1, that divides them both.
Consider the given pair of the numbers to identify which pair is relatively prime.
1. Consider 42 and 77
7 is the number which divides 42 and 77 both. Therefore, they are not relatively prime.
2. Consider 34 and 55
Since, there is no number greater than 1, which divides both the numbers. So, they are relatively prime numbers.
3. Consider 45 and 102
3 is the number divides 45 and 102 both. Therefore, they are not relatively prime.
4. Consider 99 and 123
3 is the number divides 99 and 123 both. Therefore, they are not relatively prime.
Therefore, Option B is the correct answer.
Answer:
\left(\frac{\sqrt{78}}{30},\ \frac{\sqrt{78}}{39}\ ,\frac{41\sqrt{78}}{390}\right)
Answer:
Option D is correct.
D- A number that cannot be expressed as a fraction, , where p and q are integers
Step-by-step explanation:
Irrational number:
An irrational number can not be expressed as a fraction or ratio of integers, like 
where p and q are integers
And also it can not be expressed as terminating decimal or repeating decimal
Example of the irrational number is given below.
Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .
