(a的2次方乘b的2次方乘c)÷(二分之一a乘b)=?
问题描述:
(a的2次方乘b的2次方乘c)÷(二分之一a乘b)=?
(-3m3次方乘n5次方)÷(-3m3次方乘n2次方)=?
(-2xy)6次方÷(xy)2次方=?
(2x2次方乘y)3次方乘(-7xy2次方)÷(14x4次方y3次方)=?
==
答
解
(a²b²c)÷(1/2ab)
=ab(abc)÷(1/2ab)
=2abc
(-3m³n^5)÷(-3m³n²)
=(-3m³n²)(n³)÷(-3m³n²)
=n³
(-2xy)^6÷(xy)²
=64(xy)^6÷(xy)²
=64(xy)^4
=64x^4y^4
(2x²y)³×(-7xy²)÷(14x^4y³)
=8x^6y³×(-7xy²)÷14x^4y³
=-56x^7y^5÷14x^4y³
=-4x³y²
