数学题。。。

数学题。。。要过程，不止一题！

Answer 1

2-5：=p^8*(-p^6)*p^6=-p^20
2-6: =5*p^12*(-p^6)+2*p^8*p^10=-5p^18+2p^18=-3p^18
3-1: =x^3m*y^3m

3-2: =9P^2*q^2
3-3: =9*10^8
3-4: =x^6Y^3*X^2y^6=X^8*y^9

3-5: =x^2n*y^6n+x^2n*y^6n=2*x^2n*y^6n
3-6: =x^8*y^12+x^8*y^12=2*x^8*y^12
3-7: =a^2n*(-8*b^3n)-(-1)^n*a^2n*b^3n
当n为偶数时，原式=-8*a^2n*b^3n-a^2n*b^3n=-9*a^2n*b^3n
当n为奇数时，原式=-8*a^2n*b^3n+a^2n*b^3n=-7*a^2n*b^3n
3-8： =（-0.5*2）^101*2^5=-2^5=-32
4-1: =a^7

4-2: =x^2*y^2
4-3: =t^(6-3-2)=t
4-4: =x^12/(-x^8)=-x^4
4-5: =x^12/(-x^8)=-x^4
4-6: =x^(2*4-2*2+2*2)*y^(3*4-3*2+3*2)=x^8*y^12
4-7: =(m-n)^(5-2+1-2)=(m-n)^2
5-1: =5-3+3-1=4
5-2: =2-1+4-1=4
