uekmyfhfp 5. (x^1/2* x^1/2 + 7* x^1/2) / ( x^1/2 + 7) = x^1/2(x^1/2 + 7) / (x^1/2 +7)=
=x^1/2.
3. a) =(x*x^1/24)^1/9= x^1/9 * x^1/216 = x^(1/9 + 1/216) = x^(24+1 / 216)=
x^25/216.
б) = (9/x^3 - y^2 / x^3) * x^3 = (9 - y^2) / x^3 * x^3 = 9 - y^2.
2. a) = 3/5;
б)= 27/8 - 1/16 = 54/16 - 1/16 = 53/16.
9^(-2) * 27^2/3 = 1/ 9^2 *(3^3)^2/3= 1/81 * 3^2 = 1/81 * 9/1= 1/9.
