Work: Calculate the value of equation -1^4*2^3/(4/9)^2*(-1/3)^4 .
Question type: Mathematical calculation
Solution:
-1^4*2^3/(4/9)^2*(-1/3)^4
=-1^4*2^3/0.444444^2*(-1/3)^4
=-1^4*2^3/0.444444^2*(-0.333333)^4
=1*2^3/0.444444^2*(-0.333333)^4
=1*8/0.444444^2*(-0.333333)^4
=1*8/0.197530469136*(-0.333333)^4
=1*8/0.197530469136*0.012345629629704
=8/0.197530469136*0.012345629629704
=40.500081*0.012345629629704
=0.499999 Answer:-1^4*2^3/(4/9)^2*(-1/3)^4=0.499999[4/7 Formula]
Work: Calculate the value of equation -3^3*(-5/9+8/27) .
Question type: Mathematical calculation
Solution:
-3^3*(-5/9+8/27)
=-3^3*(-0.25926)
=-27*-0.25926
=7.00002 Answer:-3^3*(-5/9+8/27)=7.00002[5/7 Formula]
Work: Calculate the value of equation abs(1/2-2/3)-abs((-2)^3*(-2))+abs((-2)^3) .
Question type: Mathematical calculation
Solution:
abs(1/2-2/3)-abs((-2)^3*(-2))+abs((-2)^3)
=abs(-0.166667)-abs((-2)^3*(-2))+abs((-2)^3)
=abs-0.166667-abs((-2)^3*(-2))+abs((-2)^3)
=abs-0.166667-abs(-2^3*(-2))+abs((-2)^3)
=abs-0.166667-abs16+abs((-2)^3)
=abs-0.166667-abs16+abs((-2)^3)
=abs-0.166667-abs16+abs(-8)
=0.166667-abs16+abs-8.000000000000000
=0.166667-16+abs-8.000000000000000
=0.166667-16+8
=-15.833333+8
=-7.833333 Answer:abs(1/2-2/3)-abs((-2)^3*(-2))+abs((-2)^3)=-7.833333[6/7 Formula]
Work: Calculate the value of equation -9*(-1/4)+0.25*25.5-(5+1/2)*(-0.25) .
Question type: Mathematical calculation
Solution:
-9*(-1/4)+0.25*25.5-(5+1/2)*(-0.25)
=-9*(-0.25)+0.25*25.5-(5+1/2)*(-0.25)
=-9*(-0.25)+0.25*25.5-5.5*(-0.25)
=-9*(-0.25)+0.25*25.5-5.5*(-0.25)
=2.25+0.25*25.5-5.5*(-0.25)
=2.25+6.375-5.5*(-0.25)
=2.25+6.375-(-1.375)
=8.625-(-1.375)
=10 Answer:-9*(-1/4)+0.25*25.5-(5+1/2)*(-0.25)=10[7/7 Formula]

Question type: Mathematical calculation
Solution:
(-2)^2-abs(-7)+3-2*(-1/2)
=-2^2-abs(-7)+3-2*(-1/2)
=-2^2-abs(-7)+3-2*(-1/2)
=-2^2-abs-7+3-2*(-0.5)
=-2^2-7+3-2*-0.5
=4-7+3-2*(-0.5)
=4-7+3-(-1)
=-3+3-(-1)
=0-(-1)
=1 Answer:(-2)^2-abs(-7)+3-2*(-1/2)=1
