Question

Prove that √2 is an irrational number and hence show that 3+5√3 is also irrational​

Answer 1

square rooted numbers like the square root of 2 are irrational because when calculated they don't equal a whole number.

Explanation:

3+5√3 = 11.66 // not whole - irrational

√2 = 1.4 // not whole - irrational

√25 = 5 // whole - rational
