Question

a)

b)

Answer 1

a)...= a^(2*(-1/4))*b^-1/4 *b^1/4 : a^2/4 =

      = a^-1/2*b^(-1/4+1/4):a^1/2=

     = a^(-1/2-1/2) * b^0 =

      = a^-1 *1 =

      = 1/a

 

b)

...=2^1/2 * (2^1/4)^1/2=

   = 2^1/2 * 2^1/8 =

   = 2^4/8 * 2^1/8=

   = 2^5/8 =

   = (8)√2^5 =

   = (8)√32          (8) -pierwiastek 8 stopnia

 

ⁿ√a^m = a^m/n

(a^m)^n=a^(m*n)

a^m*a^n=a^(m+n)

a^m:a^n =a^(m-n)
