Question

prove that 7_2 root 2 is irrational​

Answer 1

Step-by-step explanation:

we can prove that

first let us asume that root 2 is rational

so it canbe written in the form of p/q

where Q is not equals to zero and p and q are some integers so route to 2 equal to P upon q so we can transpose the q from 2

now the value of p is root 2 q by squaring both side the root should cancel and the p became p square so by the theorem we can khow that p devides q so p square is also devide

we put p square

so we put the value of p square be r

so we can see that there is no no. change the value of root 2

so our assumption is wrong root 2 is irrational
