Question

Can anyone please answer my question how to Simplify 1/root2-1

Answer 1

1/(sqrt(2) - 1)

= 1*(sqrt(2) + 1)/((sqrt(2) - 1)*(sqrt(2) + 1))

= (sqrt(2) + 1)/ (2 - 1)

= (sqrt(2) + 1) ——> Answer

Answer 2

Answer:

√2-1 or 0.414

Step-by-step explanation:

1/(√2+1)

= 1/(√2+1) x (√2-1)/(√2-1)

=  (√2-1) / (√2+1)/(√2-1)]

= (√2-1) / (√2² - 1²)

=  (√2-1) / (2-1)

= (√2-1) / 1

= √2-1  (= 1.414 - 1 = 0.414)
