Question

Prove that 2/under root 17 is a irrational number

Answer 1

Step-by-step explanation:

let us assume under root 17 is a rational number.

so under root 17 p/q.

where p and q are rational number and q is not equal to 0.

under root 17= p/q.

q under root 17= p.

RHS = rational number.

LHS = irrational number.

Which is not possible

so our assumption is wrong.

under root 17 is a irrational number.
