Answer 1

A)

4-[-0,3/0,1^3+0,2*18/(-0,3)^2]*(-1/13)^1=

=4-[ -0,3/0,001 +0,2*18/0,09]*(-1/13)=

=4-[ -300+0,2*18/0,09]*(-1/13=

=4-[-300+3,6/0,09]*(-1/13)=

=4-(-300+40)*(-1/13)=4-[-260*(-1/13)]=4-(260/13)=4-20=-16


b)-24-[1 1/4 -3 1/2]^2-8*[(1 1/4)^2-(3 1/2)^2=

=-24-[-(5/4-7/2)^2-8[(5/4)^2-(7/2)^2=

=-24-[(5-14)/4]^2-8*[25/16-49/4]=-24-(-9/4)^2-8(25/16-196/16)=

=-2481/16-8(-171/16)=-24-81/16+1368/16=-24+1287/16=(-384+1287)/16=

(-384+1287)/16=903/16=56 7/16

c)[-2^3/3+6*(-2/3)^3-4/(-5)^2 :(-2/5)^3*(1/3)^2]:(-1 1/4)^3=

[(-8/3+6*(-8/27)-4/25*-125/8*1/9]:(-5/4)^3=

[-8/3-16/9+10/36]:(-125/64)=-160/36*(-64/125)=-32/18*-32/25=-32/9*-16/25=

=512/225=2 62/225=2,27
