Question

prove that 7+2√3 pls pls fast pls fast​

Answer 1

Answer:

Let assume that 7-2root3 be rational and rational numbers are in the form of p/q form.

$7 - 2 = \sqrt{3} : p | q$

$7 - p| q = 2 \sqrt{3}$

$7q - p | q \: = 2 \ \sqrt{3}$

$7q - p | 2q \: = \sqrt{3}$

We know that root 3 is irrational and not p/q form. It contradicts the statement that it is irrational as it is p/q form.

Subtraction and multiplication of irrational number form irrational number so

7-2root3 is irrational.
