等于30414093201713378043612608166064768844377641568960512000000000000
64×0.125×0.5×0.25=(8×4×2)×0.125×0.5×0.25=(8×0.125)×(2×0.5)×(4×0.25)=1×1×1=1
0.36×(1.5×0.4)=0.36×0.6=0.216
原式=108×4.23×1.25-1.25×4.32×28=4.23×1.25×(108-28)=4.23×(1.25×80)=4.23×100=423
0.36乘5.3+3.6乘0.47=3.6乘0.53+3.6乘0.47=3.6×(0.53+0.47)=3.6
0.9乘8.4加1乘0.84=9×0.84+0.84=(9+1)×0.84=10×0.84=8.472乘1.25=9*(8*1.25)=9*10=900.36乘2.4加76乘0.036=0.36×2.
=(51÷17)×(14÷28×20)÷6=3×10÷6=5
2*3+5*9行不?
17×34+22×51=17×34+22×17×3=17×(34+66)=17×100=1700
=6.27×3.6+3.78×10×0.36=6.27×3.6+3.78×3.6=(6.27+3.78)×3.6=10.05×3.6=(10+0.05)×3.6=10×3.6+0.05×3.6=36+
3.6乘0.63+0.36乘3.7=3.6×0.63+3.6×0.37=3.6×(0.63+0.37)=3.6×1=3.6
1.原式=3.6*4.7+3.6*5.1+3.6*0.2=3.6*(4.7+5.1+0.2)=3.6*10=362.原式=1.2*3.8+1.2*3.8+1.2*24=1.2*(3.8+3.8+24)
N!=N*(N-1)*(N-2)*...3*2*1N!=N*(N-2)*(n-4)*...N!=N*(N-3)*(N-6)*...1乘4乘7乘10乘13乘...乘697乘700等于700!
1乘2乘3乘4乘5乘6乘7乘8=40320
3.6乘2.4+0.36乘58+0.18乘36=3.6×2.4+3.6×5.8+3.6×1.8=3.6×(2.4+5.8+1.8)=3.6×10=36
3.7712923×10的26次方
约分得3*2*6=36再问:要过程再答:(51/17)*(68/34)*(78/13)=3*2*6=36
解题思路:考查幂的运算解题过程:解:(1)第一次撕成2片,即21;第二次撕成4片,即22;....所以第n次撕成2n,则2n=64所以n=6所以要把这张纸撕成64片需要6次(2)撕7次后这张纸变成27
再答: 再答: 再问:嗯嗯
