能简便的要简便:-17+17÷(-1)^11-5^2X(-0.2)^3(-3\4)X[(-2)^3-(-2\3)-1\3]-13X2\3-0.34X2\7+1\3X(-13)-5\7(-3\8)X(-4)^3-0.25X(-5)X(-2)^5-10+8÷(-2)^2-(-4)X(-3)[1-(1-0.5X1\3)]X[2-(-3)^2]【写清楚步骤】
能简便的要简便:-17+17÷(-1)^11-5^2X(-0.2)^3
(-3\4)X[(-2)^3-(-2\3)-1\3]
-13X2\3-0.34X2\7+1\3X(-13)-5\7
(-3\8)X(-4)^3-0.25X(-5)X(-2)^5
-10+8÷(-2)^2-(-4)X(-3)
[1-(1-0.5X1\3)]X[2-(-3)^2]
详解 1、-17+17÷(-1)^11-5^2X(-0.2)^3
=-17-17-5^2X(-1/5)^3
=-34+(1/5)
=-34+0.2
=-33.8
2、(-3/4)X[(-2)^3-(-2/3)-1/3]
=[(-3/2^2)]X[(-2)^3+2/3-1/3]
=6-1/4
=23/4
3、-13X2/3-0.34X2/7+1/3X(-13)-5/7
=-13(2/3+1/3)-(0.34X2+5)/7
=-13-(5.68)/7
=-(9100+568)/700
=-9668/700
=-4834/350
=-2417/175
4、(-3/8)X(-4)^3-0.25X(-5)X(-2)^5
=3/2^3X2^6-1.25X4X2^3
=3X2^3-5X2^3
=(3-5)X2^3
=-2X2^3
=-2^4
=-16
5、-10+8÷(-2)^2-(-4)X(-3)
=-10+2^3X(1/2^2)-2^2X3
=-10+2-2^2X3
=2(1-5)-2X6
=2(-4-6)
=-20
6、[1-(1-0.5X1\3)]X[2-(-3)^2]
=[1-(1-1/6)]X[2-3^2]
=1/6[2-3^2]
=1/3-3/2
=-7/6
