32×17×4+84×68的简便计算

32×17×4+84×68 =(32+84)×68 =116×68 =7888 你好,本题已解答,如果满意 请点右下角“采纳答案”。

=84*184/21/92 =84/21*184/92 =4*2 =8

42乘以8加6乘以84简便计算 =42x(8+2x6) =42x20 =840

0.84×16+8.4×8.4+84= =84(0.01+0.84+1) =84×1.85 =(80+4)×1.85 =80×1.85+4×1.85 =148+7.2 =155.2

84X0.75+3/4X17-3/4 =84X0.75+0.75X17-0.75 =(84+17-1)X0.75 =100X0.75 =75

8.84+4.16-5.84+4.16的简便算法 =(8.84-5.84)+(4.16+4.16) =3+8.32 =11.32

5×84×4×5 =(5x5x4)x84 =100x84 =8400

9.84÷[4×(1.34-0.14)] =9.84÷(4*1.2) =9.84÷4.8 =2.05

12.4-(2.7-0.84) =12.4+0.84-2.7 =13.24-3+0.3 =10.54

0.54×18.4-5.4×0.84 =0.54x(18.4-8.4) =0.54x10 =5.4
