计算:(1)7m(4m²p)²÷7m²(2)(6x^4-8x³)÷(-2x²)(3)(0.25a²b-1/2a³b²-1/6a^4b³)÷(-0.5a²b)

计算:(1)7m(4m²p)²÷7m²(2)(6x^4-8x³)÷(-2x²)(3)(0.25a²b-1/2a³b²-1/6a^4b³)÷(-0.5a²b)
计算:(1)7m(4m²p)²÷7m²
(2)(6x^4-8x³)÷(-2x²)
(3)(0.25a²b-1/2a³b²-1/6a^4b³)÷(-0.5a²b)

计算:(1)7m(4m²p)²÷7m²(2)(6x^4-8x³)÷(-2x²)(3)(0.25a²b-1/2a³b²-1/6a^4b³)÷(-0.5a²b)
1、7m×16m的4次方p²÷7m²
=16m³p²
2、=6x^4÷(-2x²)-8x³÷(-2x²)
=-3x²+4x
3、=0.25a²b ÷(-0.5a²b) -1/2a³b²÷(-0.5a²b)-1/6a^4b³÷(-0.5a²b)
=-0.5+ab+1/3a²b²
