2-13分之6÷26分之9-3分之2(图解)
2-13分之6÷26分之9-3分之2(图解)
2-13分之6÷26分之9-3分之2
=2-6/13*26/9-2/3
=2-4/3-2/3
=2-6/3
=2-2
=0
2-13分之64÷26分之9-3分之2
解:
2-13分之64÷26分之9-3分之2
=2-13分之64x9分之26-3分之2
=2-9分之128-3分之2
=2-3分之2-9分之128
=3分之4-9分之128
=9分之12-9分之128
=-9分之116
2-13分之6÷26分之9=
2-13分之6÷26分之9
=2-6x26/13/9
=2-4/3
=2/3
2-13分之6÷26分之9-3分之2把详细的算式写给我
2-(6/13)/(9/26)-2/3
=2-(6/13)*(26/9)-2/3
=2-4/3-2/3
=0
(2.3回圈-13分之6/26分之9-3分之2)*1.5
原式=[7/3-(6/13)×(26/9)-2/3]×(3/2)=(7/3-4/3-2/3)×(3/2)=1/2
2-13分之6除26分之9 梯等式
2-13分之6除26分之9
=2-6/13×26/9
=2-4/3
=2/3
(6分之13)—(6分之31)—(9分之26)—(9分之43)
原式=-18/6-69/9
=-18/6-69/9
=-18/6-46/6
=-64/6
=-32/3
9分之7+(9分之2-13分之3的简便顺算的是什么
9分之7+(9分之2-13分之3)
=9分之7+9分之2-13分之3
=1-13分之3
=13分之10
(-9分之4)^13×(-1又2分之1)^26求解?
(-4/9)^13 * (-1 -1/2)^26
=(-4/9)^13 * [(-3/2)²]^13
=[(-4/9)*(9/4)]^13
=(-1)^13
=-1
