(-4 1/4)-(+3 1/8)+(-4 7/8)-(-5 1/2) 数学的脱式计算
题目是这样的吧:
(-4 又1/4)-(+3 又1/8)+(-4 又7/8)-(-5又 1/2)
=-4-1/4-3-1/8-4-7/8+5+1/2
=(-4-3-4+5)+(-1/4-1/8-7/8+1/2)
=-6-3/4
=-6又3/4
8+(-2)+(-4)+1+1+(-3)
(1,1,1).(2,4,8)...3Q
(7/20-5/36)*4-4/9 【1-(1/4+3/8)】/1/4
8(1)(2)(3)(4)
4/5+(3/8-1/2)
1,2,2,4,3,8,4,16,()()
1/2-(3/4-3/8),1/2+1/4-1/6 ,2/3+(1/2+1/4),1/2-(3/4-3/8),1/2+1/4-1/6 ,2/3+(1/2+1/4),
1/2-(3/4-3/8), 1/2+1/4-1/6 , 2/3+(1/2+1/4),1/2-(3/4-3/8), 1/2+1/4-1/6 , 2/3+(1/2+1/4),
1/2-(3/4-3/8),1/2+1/4-1/6 ,2/3+(1/2+1/4),1/2-(3/4-3/8),1/2+1/4-1/6 ,2/3+(1/2+1/4),
(+3/4)-(+6.25)-(-8 1/2)-(+0.75)-22 1/4=?1
1/(1*3)+1/(2*4)+1/(3*5)+1/(4*6)+...+1/(8*10)=?
计算:8(3^2+1)(3^4+1)(3^8+1)(3^16+1)+1
找规律:2/1、4/3、8/8、8/10、4/6( )、()、4/9
