03. Find two irrational numbers between 2 and 2.5.
Answers
If a and b are any two distinct positive rational numbers such that ab is not
a perfect square , then the irrational number √ab lies between a and b.
∴ Irrational number between 2 and 2.5 is √ 2 × 2.5 , i.e √5
Irrational number between 2 and √5 is √2 × √5 = 2(1/2) × 5(1/4)
Irrational number between √5 and 2.5 is √√5 × 2.5 =
Thus the three irrational numbers between 2 and 2.5 are √5 , 2(1/2) × 5(1/4) and (1/2) × 5 3/4 × 21/2 .
Answer:
Two irrational numbers between 2 and 2.5 are and
Step-by-step explanation:
An irrational number is a real number that can not be expressed as an integer ratio, such as √2, is an example of an irrational number. Also, neither ending nor recurring is the decimal expansion of an irrational number. The real numbers that can not be represented in p/q form are recognized as irrational numbers, where p and q are integers and q is not equal to zero.
Examples of irrational numbers are √2 and √3. However, any number in the form of p/q can be represented, p and q are integers and q s not equal to zero is regarded as a rational number.
Pi (π) is an irrational number because it is non-terminating. The approximate value of pi is 22/7 or 3.14…
Consider a and b are two distinct positive rational numbers which is not a perfect square. The irrational number √ab lies between a and b.
∴ Irrational number between 2 and 2.5 is
i.e.
Irrational number between 2 and is
Thus the two irrational numbers between 2 and 2.5 are and
