Obliczenia: a) 9/16 *(16/9)-1:(-5/2)= 1+2/5=7/5 b)[0,5*2+ 1/9:1/36]/5^(-1)= [1+4]*5=25 c)[(9/4)^(-5)*(1/9)^(-5)*(2)^(-5)]/(-1/4)^5:(-1/4)^5]:(-2)^4= [(1/4)^5*(1/2)^5]:(-2)^4= (1/8)^5*(-1/2)^4=(-1/4)^19 d){[1+ (2/22+5/22)*22]/7)*(-5/2)³= [ 1+1]*(-125/8)=2*(-125/8)=-125/4=-31 1/4

a) 9/16 * 16/9 -1 : (-5/2) = 1 - 2/5 = 3/5 c) 32/1 : 16 = 32 : 16 = 2 b) -0.25 + 4/ 0,2 = 3,75 / 0,2 =18,75 d) [1+ 7/7] : (-125/8) = 2 * (-8/125) = -16/125
