Working from the inside out: 50 = 25*2, so √50 = √25*√2 = 5√2. So 1/√50 = 1/(5√2). When teachers ask you to simplify, they often mean to write a fraction with no roots in the denominator. (Ironically, in calculus, sometimes you prefer radicals in the denominator, but worry about that later.) So we need to multiply the top and the bottom both by √2 which gives 1/√50 = √2 / (5√2 * √2) = √2 / (5*2) = √2 / 10.

50 = 25*2, so â50 = â25*â2 = 5â2. So 1/â50 = 1/(5â2)
1/â50 = â2 / (5â2 * â2) = â2 / (5*2) = â2 / 10.

(1/Square root of 50)
= 1/root(5*5*2)
=1/5root2
=1/5root2 * (root2/root2)
=root2/10
= 1.414/10
=0.1414 ##3 ^-^
