Prove that √p is an irrational number , if p is not a perfect square.​
Aneli [31]

\huge \frak \green{question}

prove that √p is an irrational number , if p is not a perfect square.

\huge \frak \red{answer}

Let us assume, to the contrary, that √p is rational. So, we can find coprime integers a and b(b ≠ 0) such that :-

=> √p = a/b

=> √p b = a

=> pb² = a² ….(i) [Squaring both the sides]

=> a² is divisible by p

=> a is divisible by p So, we can write a = pc for some integer c.

Therefore,

a² = p²c² ….[Squaring both the sides]

=> pb² = p²c² ….[From (i)]

=> b² = pc²

=> b² is divisible by p

=> b is divisible by p

=> p divides both a and b.

=> a and b have at least p as a common factor.

But this contradicts the fact that a and b are coprime. This contradiction arises because we have assumed that √p is rational. Therefore, √p is irrational.

Answer:

First 25% 10 - 22.5

Next 25% 22.5 - 35

Third 25% 35 - 47.5

Last 25% 47.5 - 60

Step-by-step explanation:

First get the median of the entire data.

From the median, you split the data into two and find the median for both sections.

Finally, your smallest median is your first 25% and so on.
