1.已知X^3a次方=3,求X^6a次方+X^4a次方.x^5a的值.
X^6a次方+X^4a次方·x^5a
=(x^3a)²+X^9a
=(x^3a)²+(X^3a)³
=3²+3³
=9+27
=36
2.[-1/3(x-y)]^2*[-3/2(y-x)]^2*[2(y-x)]^3
=(1/9)(x-y)²×(9/4)(x-y)²×[-8((x-y)³]
=-2(x-y)^7
3.3(a+b)^2*[2(-a-b)^3]+[2(a+b)]^3*(-a-b)^2
=3(a+b)²×[-2(a+b)³]+[2(a+b)]³×(a+b)²
=[-6(a+b)^5]+[2(a+b)^5]
=-4(a+b)^5
4.2ab*3a^b+(-a^b)*(3ab)
=[6ba^(1+b)]-[3ba^(1+b)]
=3ba^(1+b)
作为家长，我觉得你很有才
