Question

prove that 2-3/5 is irrational​

Answer 1

Answer:

Prove that 3 +5 is irrational.

Rational numbers are the ones that can be expressed in qp form where p,q are integers and q isn't equal to zero. As p and q are integers RHS is also rational. As RHS is rational LHS is also rational i.e 5 is rational. But this contradicts the fact that5 is irrational.

Step-by-step explanation:

this is not the same solution which u r asking but the formula for doing is same...~~~

Answer 2

Answer:

Step-by-step explanation:

let it be rational number

therefore it can be written in form of a and b where a and b are co-prime numbers.

2√3=5a/b

5a/b is rational number as it is of the form p/q which is a rational number.

but we know that √3 is irrational number so our assumption is wrong.

2√3/5 is irrational.

hope this helps u :-)
