[( 2/1*1/8+15/4) : 5/2+1/2] :1/30=

[(2/8+15/4):5/2+1/2] :1/30=

[(1/4+15/4)*2/5 +1/2] :1/30=

(16/4 *2/5+1/2 ) :1/30=

(4*2/5+1/2):1/30=

(²⁾8/5+⁵⁾1/2) :1/30=

(16/10+5/10):1/30=

(²⁾2/3+³⁾1/2)²=

(4/6+3/6)²=

=(7/6) ²

=(⁴⁾4/9+⁹⁾1/4)+8/3*1/2=

= (16/36+9/36)+4/3=

=25/36+¹²⁾4/3

=25/36+48/36

= 73/36
