let 7-2 root 3 a rational number. so, it can be written in the form of p/q. HERE [(p/-2q)-7] IS A RATIONAL NO. ... THEREFORE, 7-2 ROOT 3 IS IRRATIONAL.

The Brainliest Answer! A rational number can be written in the form of p/q where p,q are integers. p,q are integers then (p²-47q²)/6q² is a rational number. ... Hence,√2-3√5 is irrational number.

let us assum that 5-√3 is rational number so we can find two integers a , b. Where a and b are two co - primes number. So it arise contradiction due to our wrong assumption that 5 - √3 is rational number. Hence, 5 -√3 is irrational number.

Since p and q are integers, so the fraction on the right-hand side of the above equation is rational. This implies that √3 is also rational, which is a contradiction. Thus, our assumption is wrong and hence is rational. Question : Prove that root 3-root 2 is irrational.

So 1/2+root 3 = a/b where a and b are irrationals. since rhs is a rational number root 3 should be also rational . ... So our assumption is wrong and hence we conclude that is irrational.

Let 2+√3 is a rational number. A rational number can be written in the form of p/q. p,q are integers then (p-2q)/q is a rational number. But this contradicts the fact that √3 is an irrational number.

So 3+2√5 = a/b where a,b are integers and are co primes and b is not equal to 0. ... => √5 is rational which is a contradiction since √5 is irrational. So our assumption that 2+3√5 is rational is wrong. So 2+3√5 is irrational.

Explanatory Answer The contradiction is because of the incorrect assumption that (5 + 3√2) is rational. So, 5 + 3√2 is irrational.

A Glowing Geometric Proof that Root-2 is Irrational. It was a great shock to the Pythagoreans to discover that the diagonal of a unit square could not be expressed as a ratio of whole numbers.

Now as here 6*7=42 is not a perfect squre , is an irrational number. So is the required irrational. Then if x is such that. then is iraational between 6 and 7.

There must always be a simplest rational number and the original assumption that √2 is equal to p/q does not obey this rule. So it can be stated that a contradiction has been reached. ... Hence √2 is not a rational number. Thus, Euclid succeeded in proving that √2 is an Irrational number.

A proof that the square root of 2 is irrational. Let's suppose √2 is a rational number. Then we can write it √2 = a/b where a, b are whole numbers, b not zero. We additionally assume that this a/b is simplified to lowest terms, since that can obviously be done with any fraction.

Because √2 is not an integer (2 is not a perfect square), √2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not the square of a natural number is irrational.

A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.

°•Therefore ,2-3√5 can be written in the form of a/b. where a and b are co-prime numbers. Where -√5 is an irrational number and a-2b/3 is a rational number. Hence √5 is irrational.
