1)a. 0,000061x0:19/76+0,125= 0:19/76+0,125= 0+0,125=0,125 b.0.5x[2/7-0.1(6)]:2.5= 0.5x

a) (0,25)^21:(0,25)^19+0,125=
(0,25)²+0,125=
(1/4)²+1/8=
1/16+1/8=3/16=0,1875

b) 1/2.(1/3+1/4-15/90):5/2=
1/2.(1/3+1/4-1/6).2/5=
1/2.5/12.2/5=1/12

c) 6/90+15/64.128/100-2(1/8-75/900)=
1/15+15/64.32/25-2(1/8-1/12)=
1/15+3/10-2/24=
1/15+3/10-1/12=
(4+18-5)/60
17/60
