Help Me Please.

√(1/4) = 1/2 (or 0.5) If you think about it square root of 1 is 1 and the square root of 4 is 2. 

0.5/4√1/8 = √2/4 

sqrt 1/4   /   (1/8)^1/4

= 1/2   /   (1/2^3)^1/4

= 1/2   /  1/2^3/4

=2^-1  * 2^3/4

= 2^-(1/4)

1/2^(1/4)

=.841

√1/4 /  ⁴√1/8

Manuel....I find these easiest if we convert to exponential form, first...so we have

(1/4)^(1/2)  / ( 1/8)^(1/4)   note  that we can write

(1 / 2^2)^(1/2)  / (1 / 2^3)^(1/4)

( 1 / 2)  / ( 1/ 2^(3/4) )   ...so we have

(1/2)^1  *  (1/2)^(-3/4)  =

(1/2)^(1/4)   =  ⁴√(1/2)

Thank you all!!
